I. Introduction

There are currently 47 states and four territories with some form of a medical cannabis law, but the rights and privileges they extend to medical cannabis patients vary among them. As a result, patients who travel for personal or employment reasons can find themselves unsure as to how to access medical cannabis in an unfamiliar place. Given the importance of patients knowing the laws regarding medical cannabis in the jurisdictions they visit, Americans for Safe Access (ASA), the largest national member-based organization promoting safe and legal access to cannabis for therapeutic use and research, has created The Medical Cannabis Patient’s Guide for U.S. Travel. This guide will help patients understand the laws in the states and territories in which they are eligible to obtain medical cannabis so that they may do so safely and legally.

II. Know Before You Go

Before traveling, it is important for patients to review the most up-to-date information for the jurisdiction(s) they will be visiting, as laws and regulations are subject to change. It is also important to remember that cannabis products cannot be taken out of the jurisdiction in which they were purchased.

Laws protecting patients vary from jurisdiction to jurisdiction and, in some cases, among counties within a state, but no matter what jurisdiction they live in, medical cannabis patients are always violating federal law when in possession of cannabis, which is federally classified as a Schedule I controlled substance. While many of the jurisdictions with medical cannabis programs offer some form of reciprocity to visiting medical cannabis patients, meaning they recognize the protections that have been granted to these patients by other jurisdictions, traveling across state lines with any amount of cannabis is also a federal crime. The federal government can prosecute a patient who is caught transporting cannabis across state lines for drug trafficking; this holds true even if the patient is transporting cannabis between two jurisdictions that have implemented medical cannabis programs. It also should be noted that several of the jurisdictions in which cannabis is legal have explicitly outlawed the importation and/or exportation of cannabis across their borders.

While the probability of arrest by federal law enforcement officers may be low, the penalties are severe: at a minimum, individuals charged with the trafficking of cannabis face up to five years in prison and a fine of up to $250,000 for a first offense or double those amounts for a second offense. Historically, these penalties have been reserved for high-volume distributors of cannabis, not medical patients, but because the interstate transport of cannabis remains a federal crime, it is important to be aware of the potential consequences.

Safeguarding Rights

A medical cannabis patient who has been stopped by the police should never give them permission to conduct a search. If officers try to search a patient’s car or belongings, the patient should loudly and clearly state: “I do not consent to a search.” This may not stop the police from conducting a search, but if the search is illegal, any evidence resulting from it may be inadmissible in court. If the search is consented to, any evidence it uncovers would be admissible. While patients should not consent to a search, they also should not physically resist officers in any way, even if the search is illegal; doing so may result in charges of resisting arrest or assault on a police officer and/or may lead to the patient’s injury or death. If the police conduct a search over a patient’s objections, the patient should continue to state "I do not consent to this search" loudly enough for the officers and all witnesses to hear.

Information on rights as a patient, existing federal laws, avoiding law enforcement encounters, preparing for law enforcement encounters, and navigating the legal system after an encounter is available at https://www.safeaccessnow.org/knowing_your_rights.

Using a Retail Dispensary

Patients traveling to states that permit the adult use of cannabis but do not extend reciprocity to non-resident patients may have to obtain cannabis from an adult-use dispensary. While some dispensaries cater more to patients than others, patients who are unsure about the suitability of specific options offered by a dispensary should inform staff of their patient status and ask for help identifying appropriate products for their conditions.

Product safety testing requirements can vary from jurisdiction to jurisdiction, and one jurisdiction may have different testing requirements for adult-use and medical cannabis products. Appropriate certifications from an independent oversight body, such as ASA’s Patient Focused Certification, can help patients identify companies that voluntarily subject themselves to robust oversight and products that are well made and accurately labeled. A list of PFC-certified companies is available at https://patientfocusedcertification.org/companies.

Storing Cannabis

After obtaining cannabis at their destination, patients should ensure that it is stored properly. Light, heat, and oxygen can degrade cannabinoids and terpenes. Excessive moisture in a product can promote spoilage and fungal growth. Generally, cannabis floral material and products derived therefrom should be kept in a container that minimizes exposure to these factors and should be stored in a climate-controlled setting to avoid elevated temperatures and humidity. To protect the contents within and to minimize the release of odor, containers should be rigid, airtight, and made out of a non-absorptive material (e.g., glass, stainless steel) that is appropriate for the type of product in question.

Helpful Tips for Travel

Patients are encouraged to:

  • Maintain a current doctor's recommendation.
  • Keep their medical cannabis ID card and/or a copy of their doctor’s recommendation on their person at all times.
  • Keep another copy of their doctor’s recommendation and/or medical cannabis ID card in their luggage when they travel.
  • Memorize their physician's and lawyer's phone numbers or write them down and keep them with their medical cannabis ID card and/or doctor's recommendation.
  • Contact dispensaries in their destination jurisdiction(s) prior to travel to determine where appropriate cultivars and products can be obtained.

III. Planes, Trains, and Automobiles

The Transportation Security Administration (TSA) allows the transport of prescribed, FDA-approved cannabis products (e.g., Epidiolex) as well as the transport of CBD products manufactured pursuant to the Agriculture Improvement Act of 2018, which is also known as the 2018 farm bill. Products that fall into the latter category must be made from industrial hemp, which cannot contain more than 0.3% tetrahydrocannabinol (THC). ASA strongly encourages patients to avoid flying with cannabis-derived products that were not made from industrial hemp unless they have a prescription for an FDA-approved product.

The TSA’s screening procedures are focused on detecting security threats to aviation and passengers. While TSA agents do not actively search for cannabis or other drugs, they are required to report the discovery of such substances to law enforcement.1M Some major airports have cannabis “amnesty boxes” where patients can dispose of any cannabis remaining in their possession before boarding their flights. In the absence of such amnesty boxes, patients may wish to discreetly dispose of any remaining cannabis in a trash can before undergoing security screening.

Some airlines, including Delta and American, have created specific policies prohibiting the transport of cannabis on their aircraft while acknowledging that a growing number of states have legalized cannabis for medical and/or recreational use.2,3 Patients may wish to check their airlines’ baggage policies for any cannabis-specific information.

Operators of other popular forms of transportation have also created restrictive policies regarding cannabis. Amtrak bans “the use or transportation of marijuana in any form for any purpose… even in states or countries where recreational use is legal or permitted medically.”4 Greyhound’s policy prohibits “alcohol, drugs, or weapons anywhere on the bus (including in your checked baggage).”5 Patients should check their carriers’ policies for more information.

Popular ridesharing companies seem to be staking out different, and at times self-contradictory, approaches to cannabis. Uber states that using its app “to commit any crime - such as transporting drugs… or to violate any other law is strictly prohibited,”6 but the company has sponsored cannabis-related celebrations.7 Lyft, on the other hand, has a zero-tolerance drug and alcohol policy for its drivers but only prohibits passengers from transporting open containers of alcohol.8 Additionally, the company has sponsored cannabis-related events and has offered discount codes on April 20th (i.e., 4/20, a day of significance to some cannabis consumers) in the past.9,10 It is important to recall, however, that rideshare drivers are using their personal vehicles and that some may object to the smell of cannabis in their car. To be respectful of the driver and his or her vehicle, patients are encouraged to explore scent-reducing or -eliminating storage and transportation solutions.

To protect others and preserve their own safety and liberty, patients should never drive under the influence of any substance that may negatively impact their driving ability, including cannabis. Patients who intend to drive while in possession of cannabis should make sure their vehicle registration, driver’s license, and license plates are unexpired and that all lights (including turn signals) are operational. Observing basic rules of the road, such as using a turn signal when changing lanes and keeping license plates current, can help to minimize the potential for interaction with law enforcement. When driving, patients should keep cannabis locked in the trunk. In some jurisdictions where cannabis is legal, driving with cannabis that is stored anywhere other than in the trunk - including in a locked glove compartment - is illegal.

IV. Reciprocity

As was touched upon in Section II, reciprocity refers to laws providing some measure of legal protection for non-resident medical cannabis patients. These laws generally require that patients carry documentation of their status in their home jurisdiction’s program, such as their medical cannabis cards. Reciprocity is important for traveling patients, patients who are seeking specialty treatments outside of their home jurisdiction, and patients who need to stay in the care of friends or family out of state, but historically, many jurisdictions have imposed residency requirements for participation in medical cannabis programs and the benefit of legal protections. The adoption of reciprocity provisions by more jurisdictions in recent years has given medical cannabis patients and their caregivers the ability to travel more freely. However, not all reciprocity programs are created equal - some states only provide basic protections, while others grant visiting patients the same rights as resident patients. It is important for patients to know where, and how, they can legally access cannabis while traveling.

Access to Medical Cannabis by Jurisdiction

Alaska

Alaska’s medical cannabis law does not contain provisions for dispensaries, but the legalization of cannabis in the state has resulted in the creation of a regulated sales system that serves residents and visitors alike. Thus, visiting patients who are 21 or older can obtain cannabis from a retail dispensary. Unfortunately, this leaves the needs of visiting minor patients unaddressed. While Alaska doesn’t have a reciprocity program, patients should still travel with their medical cannabis ID cards (or their equivalents) in case of any potential interaction with law enforcement.

  • Resident Patient Possession Limit: 1 oz of usable cannabis
  • Resident Patient Purchase Limit: 1 oz of usable cannabis
  • Visiting Patient Possession Limit: 1 oz of usable cannabis
  • Visiting Patient Purchase Limit: 1 oz of usable cannabis

Arizona

Arizona allows visiting patients with a registry ID card or its equivalent to possess and use cannabis, but they are not eligible to obtain cannabis from any of Arizona’s dispensaries because they cannot be added to the electronic verification system that dispensaries are required to access before dispensing cannabis.

  • Resident Patient Possession Limit: 2.5 oz of usable cannabis and, if authorized, 12 cannabis plants
  • Resident Patient Purchase Limit: 2.5 oz of usable cannabis per 14-day period
  • Visiting Patient Possession Limit: 2.5 oz of usable cannabis
  • Visiting Patient Purchase Limit: N/A

Arkansas

Arkansas allows qualified visiting patients to use the state’s medical cannabis program. Non-residents and those who have been residing in Arkansas for fewer than 30 days are eligible. The patients must possess a registry ID card or its equivalent from another jurisdiction and have a qualifying condition that has been approved in Arkansas. Additionally, visiting patients must fill out the visiting patient application and pay a non-refundable $50.00 fee. It is critical that patients who intend to travel to Arkansas plan ahead; the processing of a visiting patient card may take up to two weeks. Once issued, the card is valid for 30 days.

Once their applications have been approved, visiting patients can obtain cannabis in the state’s dispensaries if they show their AR registry card or its equivalent from their home state. The dispensary will retain a copy of the card as well as a second form of ID, such as a driver’s license, and will require visiting patients to sign a form affirming that they have been diagnosed by a healthcare provider to have a qualifying condition.

  • Resident Patient Possession Limit: 2.5 oz of usable cannabis per 14 days
  • Resident Patient Purchase Limit: 2.5 oz of usable cannabis per 14 days
  • Visiting Patient Possession Limit: 2.5 oz of usable cannabis per 14 days
  • Visiting Patient Purchase Limit: 2.5 oz of usable cannabis per 14 days

California

California has legalized the adult use of cannabis but does not recognize medical cannabis cards from other states, which poses a problem for minor patients given that they cannot access retail dispensaries. While California doesn’t have a reciprocity program, patients should still travel with their medical cannabis ID cards (or their equivalents) in case of any potential interaction with law enforcement.

  • Resident Patient Possession Limit: 8 oz of dried flower and 6 mature cannabis plants or 12 immature cannabis plants unless a physician recommends that these limits be higher to be consistent with patient needs
  • Resident Patient Purchase Limit: 8 oz of dried flower or the plant conversion per day
  • Visiting Patient Possession Limit: 1 oz of dried flower or 8g of concentrate
  • Visiting Patient Purchase Limit: 1 oz of dried flower or 8g of concentrate may be purchased from retail dispensaries per day by those aged 21 or over

Colorado

Colorado has legalized the adult use of cannabis, but its medical cannabis program is limited to residents. Individuals who are at least 21 years old may purchase cannabis from a retail dispensary, but visiting minor patients cannot access cannabis in the state. While Colorado doesn’t have a reciprocity program, patients should still travel with their medical cannabis ID cards (or their equivalents) in case of any potential interaction with law enforcement.

  • Resident Patient Possession Limit: 2 oz
  • Resident Patient Purchase Limit: 2 oz of dried flower and 6 immature cannabis plants or cannabis seeds per day unless a physician provides documentation that more is necessary
  • Visiting Patient Possession Limit: 1 oz of dried flower, 8g of cannabis concentrate, or 800mg of cannabis edibles
  • Visiting Patient Purchase Limit: 1 oz of dried flower, 8g of cannabis concentrate, or 800mg of cannabis edibles may be purchased from retail dispensaries per day by those aged 21 or over

District of Columbia

On August 8th, 2019, the mayor of the District of Columbia announced that the District would extend reciprocity to patients from any state that issues medical cannabis cards or their equivalents. Prior to that date, DC extended reciprocity to patients from states with medical cannabis programs that were substantially equivalent to the District’s: Colorado, Connecticut, Delaware, Florida, Hawaii, Illinois, Maine, Maryland, Massachusetts, Michigan, Montana, New Hampshire, New Jersey, North Dakota, Ohio, Oregon, Pennsylvania, Rhode Island and Washington State. The new states added by this rulemaking include Alaska, Arizona, Arkansas, California, Nevada, New Mexico, New York, and Vermont. As of August 8th, Louisiana, Minnesota, Oklahoma, and West Virgina cards are under review but are expected to be accepted in the District’s program.

Visiting patients may present their unexpired medical cannabis cards (or their equivalents) and another form of unexpired photo ID at any of DC’s medical dispensaries in order to obtain cannabis. Note that dispensaries will not be permitted to dispense medical cannabis to visiting patients if the DC Department of Health determines that there is a shortage of medical cannabis or if the real-time electronic records system is inactive.

  • Resident Patient Possession Limit: 4 oz of dried flower or its equivalent when sold in any other form
  • Resident Patient Purchase Limit: 4 oz of dried flower or its equivalent per 30 days
  • Visiting Patient Possession Limit: 4 oz of dried flower or its equivalent when sold in any other form
  • Visiting Patient Purchase Limit: 4 oz of dried flower or its equivalent per 30 days

Guam

Guam legalized medical cannabis in 2014 and the adult use of cannabis in 2019, but dispensaries are not yet operational. Patients and persons 21 years of age and older and permitted to cultivate their own cannabis; patients must register with and pay a fee to the Department of Public Health and Social Services (DPHSS) for permission to cultivate, but no such requirement exists for those taking advantage of the personal cultivation provisions of the 2019 cannabis legalization bill. That legislation also legalizes the transfer of up to one ounce of cannabis, eight grams of concentrate, or up to 800mg of THC in cannabis-infused products to another person who is at least 21 years old without remuneration.

Until dispensaries are operational, it seems as though visiting patients who are at least 21 years old would have to attempt to procure gifted cannabis from those who cultivate it at home and that minors would be unable to access it. While minors can be registered as patients, the 2019 cannabis legalization law does not provide for the transfer of cannabis to those under the age of 21, regardless of patient status. Once disperies are open, access to medical cannabis will become easier for visitors.

In 2018, Guam’s medical cannabis law was amended to remove the residency requirement for qualified patients. Visiting patients may register with the DPHSS by obtaining a written certification from a Guamanian healthcare practitioner, completing a qualified patient registration form, and paying the $15 registration fee. Cards will not be required to participate in the program. Qualified patients that have registered with the DPHSS may legally possess 2.5 oz of dried cannabis or its equivalent; adults 21 years of age and older may possess up to 1 oz or its equivalent.

  • Resident Patient Possession Limit: 2.5 oz of dried cannabis or its THC product equivalent
  • Resident Patient Purchase Limit: Once dispensaries are operational, 2.5 oz of dried cannabis or its THC product equivalent per 14-day period unless higher amount approved by physician
  • Visiting Patient Possession Limit: 2.5 oz of dried cannabis or its THC product equivalent
  • Visiting Patient Purchase Limit: Once dispensaries are operational, 2.5 oz of dried cannabis or its THC product equivalent per 14 -day period unless higher amount approved by physician

Hawaii

Hawaii provides a comprehensive online application process for out-of-state patients who are certified in their home state as having a debilitating medical condition as defined in Hawaii State Law to obtain a Hawaii 329 Registration Card, which grants access to medical cannabis dispensaries. A visiting patient who wishes to obtain a 329 card must submit his or her valid, unexpired medical cannabis card and an additional form of state-government-issued ID from the same jurisdiction that issued, and bearing the same name as, the medical cannabis card. If the out-of-state card does not have an expiration date, the patient will be required to submit additional documentation. Unlike some other jurisdictions, Hawaii will not accept a medical cannabis certification/recommendation in lieu of a medical cannabis card. Note that passports and military ID cards are not accepted forms of ID for the purposes of obtaining a 329 card.

Hawaii 329 Registration Cards for out-of-state patients are valid for 60 days, and the patient may apply for a 329 card up to 60 days before the requested start date. Visiting patients are limited to two 60-day terms per calendar year, and there is a non-refundable fee of $49.50 per application.

The Hawaii Department of Health has put together an instructional video and a checklist for visiting patients and urges visiting patients to ensure that the island they are traveling to has a dispensary with the products they need, as traveling between islands could involve crossing a federal waterway. This should be done prior to submitting an application.

  • Resident Patient Possession Limit: 4 oz of usable cannabis or its equivalent
  • Resident Patient Purchase Limit: 4 oz of usable cannabis or its equivalent per 15-day period
  • Visiting Patient Possession Limit: 4 oz of usable cannabis or its equivalent
  • Visiting Patient Purchase Limit: 4 oz of usable cannabis or its equivalent per 15-day period

Illinois

Illinois does not extend reciprocity to medical cannabis patients. However, beginning January 1, 2020, non-residents will be able to purchase and possess up to 15 grams of cannabis flower, 2.5 grams of cannabis concentrate, and 250 mg of THC in cannabis-infused products. Illinois residents who are not medical cannabis patients will be able to purchase and possess double these amounts. While Illinois doesn’t have a reciprocity program, patients should still travel with their medical cannabis ID cards (or their equivalents) in case of any potential interaction with law enforcement.

  • Resident Patient Possession Limit: 2.5 oz of usable cannabis, unless a physician waiver is obtained
  • Resident Patient Purchase Limit: 2.5 ounces of usable cannabis per 14 days, unless a physician waiver is obtained
  • Visiting Patient Possession Limit: Beginning January 1, 2020, adults 21 and over may possess 15 grams of cannabis flower, 250 mg of THC-infused edible cannabis products, and 2.5 grams of concentrated cannabis product
  • Visiting Patient Purchase Limit: Beginning January 1, 2020, adults 21 and over may purchase 15 grams of cannabis flower, 250 mg of THC-infused edible cannabis products, or 2.5 grams of concentrated cannabis product

Maine

Medical cannabis patients from the jurisdictions to which Maine extends reciprocity may use their home-jurisdiction patient ID cards and photo identification to purchase cannabis through Maine’s medical program. As of July 24, 2019, the 25 jurisdictions to which Maine extends reciprocity include: Alaska, Arizona, Arkansas, California, Connecticut, the District of Columbia, Florida, Hawaii, Illinois, Iowa, Maryland, Michigan, Minnesota, Montana, Nevada, New Hampshire, New Jersey, New Mexico, New York, North Dakota, Oklahoma, Oregon, Rhode Island, Vermont, and Washington.

Once the state’s adult-use framework is in place, all patients will be able to obtain cannabis while in Maine.

  • Resident Patient Possession Limit: 8 pounds of harvested cannabis (which includes all prepared forms), 6 mature cannabis plants, 12 immature cannabis plants, and unlimited cannabis seedlings
  • Resident Patient Purchase Limit: 2.5 oz of usable cannabis
  • Visiting Patient Possession Limit: 2.5 oz of harvested cannabis in a 15-day period
  • Visiting Patient Purchase Limit: 2.5 oz of usable cannabis, cannabis products, or a combination thereof every 15 days

Massachusetts

Massachusetts does not recognize medical cannabis cards issued by other jurisdictions, but individuals who are at least 21 years old may obtain cannabis through the state’s adult-use market. Unfortunately, this leaves the needs of visiting minor patients unaddressed. While Massachusetts doesn’t have a reciprocity program, patients should still travel with their medical cannabis ID cards (or their equivalents) in case of any potential interaction with law enforcement.

  • Resident Patient Possession Limit: 10 oz of cannabis or its equivalent every 60 days unless a healthcare provider determines and certifies that a different amount is required
  • Resident Patient Purchase Limit: 10 oz of cannabis or its equivalent every 60 days unless a healthcare provider determines and certifies that a different amount is required
  • Visiting Patient Possession Limit: 1 oz of cannabis on one’s person if age 21 or over, except not more than 5g may be in the form of a cannabis concentrate
  • Visiting Patient Purchase Limit: 1 oz of cannabis or 5g of cannabis concentrate may be purchased from retail dispensaries per day by those aged 21 or over

Michigan

Michigan gives the same force and effect to medical cannabis cards issued outside of the state as it does to its own cards, meaning that patients may use their home-jurisdiction medical cannabis cards and photo IDs to make purchases at the state’s medical cannabis dispensaries. Michigan also has legalized the adult use of cannabis but has yet to implement the framework necessary for such sales.

  • Resident Patient Possession Limit: 2.5 oz of usable cannabis or its equivalent and 12 cannabis plants
  • Resident Patient Purchase Limit: 2.5 oz of usable cannabis per day, not to exceed 10 oz per month
  • Visiting Patient Possession Limit: 2.5 oz of usable cannabis or its equivalent and 12 cannabis plants
  • Visiting Patient Purchase Limit: 2.5 oz of usable cannabis per day, not to exceed 10 oz per month

Nevada

Nevada allows reciprocity through its medical program and also permits the adult use of cannabis. Non-resident patients may use their home-jurisdiction medical cannabis cards and photo IDs to purchase medical cannabis from dispensaries. The purchase and possession limits are higher for medical patients than for other adult consumers of cannabis.

  • Resident Patient Possession Limit: 2.5 oz of usable cannabis per 14-day period, an amount of edible cannabis products and cannabis-infused products that is equivalent to 2.5 oz of usable cannabis (with a cap of 10g of THC) per 14-day period, and 12 cannabis plants
  • Resident Patient Purchase Limit: 2.5 oz of usable cannabis per 14-day period and an amount of edible cannabis products and cannabis-infused products that is equivalent to 2.5 oz of usable cannabis (with a cap of 10g of THC) per 14-day period
  • Visiting Patient Possession Limit: 2.5 oz of usable cannabis per 14-day period and an amount of edible cannabis products and cannabis-infused products that is equivalent to 2.5 oz of usable cannabis (with a cap of 10g of THC) per 14-day period
  • Visiting Patient Purchase Limit: 2.5 oz of usable cannabis per 14-day period and an amount of edible cannabis products and cannabis-infused products that is equivalent to 2.5 oz of usable cannabis (with a cap of 10g of THC) per 14-day period

New Hampshire

Patients visiting New Hampshire from another jurisdiction may possess cannabis but are unable to purchase it in the state’s dispensaries. To benefit from New Hampshire’s medical cannabis law, the visiting qualifying patient must produce a registry ID card (or its equivalent) from another state and a statement from their healthcare provider stating that the patient has a qualifying condition that is recognized by New Hampshire law. The visiting patient provisions only apply to those who are not residents or to residents who have been in the state for fewer than 30 days. Visiting patients cannot receive cannabis via the state’s gifting provisions or cultivate medical cannabis in New Hampshire.

  • Resident Patient Possession Limit: 2 oz of usable cannabis
  • Resident Patient Purchase Limit: 2 oz of usable cannabis every 10 days
  • Visiting Patient Possession Limit: 2 oz of usable cannabis
  • Visiting Patient Purchase Limit: N/A

New Mexico

On August 5, 2019, a New Mexico judge ruled that the state’s Department of Health has to issue medical cannabis cards to non-residents because of how the state redefined “qualified patient” when it amended the Compassionate Use Act in March 2019. However, the Governor, Michelle Lujan Grisham, has intervened in this lawsuit on the premise that it was not the intent of the New Mexico regulations to allow any non-resident to obtain a medical cannabis card in the state. Rather, the intent was to provide a traditional reciprocity program through which residents from other states could access New Mexico’s program with a registry ID card or its equivalent from another state. This case is ongoing, so it is important to follow updates on the New Mexico Department of Health’s website. Reciprocity regulations must be in place by March 1, 2020.

New Mexico expresses possession limits in units. One unit of usable cannabis is equivalent to one gram of dried usable cannabis plant material or to 0.2 grams (200 milligrams) of THC for cannabis-derived products.

  • Resident Patient Possession Limit: 230 units per 90-day period
  • Resident Patient Purchase Limit: 230 units per 90-day period
  • Visiting Patient Possession Limit: TBD
  • Visiting Patient Purchase Limit: TBD

Oklahoma

Oklahoma offers temporary patient licenses for both minor and adult visiting patients. The temporary licenses are valid for 30 days and may be renewed, but the expiration date of the temporary license cannot be later than the expiration date of the patient’s medical cannabis ID card. To obtain a temporary ID card, a patient must submit a digital color copy of their home-jurisdiction medical cannabis card and a digital color copy of a driver's license, passport, or state-issued ID. The visiting patient also must submit a passport-style photograph and pay a non-refundable $100 application fee by credit or debit card. The processing of a temporary patient license application can take up to 14 days, so it is important for travelers to plan ahead.

Detailed instructions for obtaining a temporary card are available on the Oklahoma Medical Marijuana Authority’s website.

  • Resident Patient Possession Limit: 3 oz of cannabis on one’s person; 1 oz of cannabis concentrate; 72 oz of cannabis edibles; 6 mature cannabis plants; 6 cannabis seedlings; and 8 oz of cannabis in one’s residence
  • Resident Patient Purchase Limit: 3 oz of usable cannabis, 1 oz of cannabis concentrate, 72 oz of cannabis-infused products, 6 mature cannabis plants, and 6 cannabis seedlings in a single transaction
  • Visiting Patient Possession Limit: 3 oz of cannabis on their person; 1 oz of cannabis concentrate; 72 oz of cannabis edibles; 6 mature cannabis plants; 6 cannabis seedlings; and 8 oz of cannabis in their residence
  • Visiting Patient Purchase Limit: 3 oz of usable cannabis, 1 oz of cannabis concentrate, 72 oz of cannabis-infused products, 6 mature cannabis plants, and 6 cannabis seedlings in a single transaction

Oregon

Oregon does not recognize medical cannabis cards from other states, but individuals who are at least 21 years of age may purchase cannabis in the state’s retail dispensaries. Unfortunately, this leaves the needs of visiting minor patients unaddressed. While Oregon doesn’t have a reciprocity program, patients should still travel with their medical cannabis ID cards (or their equivalents) in case of any potential interaction with law enforcement.

  • Resident Patient Possession Limit: 24 oz of usable cannabis, 16 oz of cannabinoid product in solid form, 72 oz of cannabinoid product in liquid form, 16 oz of cannabinoid concentrate, 1 oz of cannabinoid extracts, 6 mature cannabis plants, and 12 immature cannabis plants
  • Resident Patient Purchase Limit: 24 oz of usable cannabis, 16 oz of a medical cannabinoid product in solid form, 72 oz of a medical cannabinoid product in liquid form, 16 oz of cannabinoid concentrate (whether sold alone or contained in an inhalant delivery system), 5g of a cannabinoid extract (whether sold alone or contained in an inhalant delivery system), 4 immature cannabis plants, and 50 cannabis seeds in one purchase or within one day
  • Visiting Patient Possession Limit: 1 oz of usable cannabis on their person in public, 8 oz of usable cannabis in their home, 16 oz of a cannabinoid product in solid form, 72 oz of a cannabinoid product in liquid form, 5g of cannabinoid extracts or concentrates (whether sold alone or contained in an inhalant delivery system), 4 cannabis plants, and 10 cannabis seeds
  • Visiting Patient Purchase Limit: 1 oz of usable cannabis, 16 oz of a cannabinoid product in solid form, 72 oz of a cannabinoid product in liquid form, 5g of cannabinoid extracts or concentrates (whether sold alone or contained in an inhalant delivery system), 4 immature cannabis plants, and 10 cannabis seeds may be purchased from retail dispensaries per day by those aged 21 or over

Puerto Rico

Puerto Rico extends reciprocity to medical cannabis patients with unexpired medical cannabis recommendations and medical cannabis ID cards from U.S. jurisdictions for up to 30 days as long as those jurisdictions maintain a database that allows verification of patient status and make such information available to Puerto Rican authorities and dispensaries. Puerto Rico does not impose a residency requirement for qualifying patients, meaning that non-resident patients may obtain a Puerto Rican medical cannabis card by visiting an authorized healthcare provider and completing the application process. Given that reciprocity is only extended for up to 30 days, non-resident patients who need access to medical cannabis beyond that period must be certified as qualified patients under the laws and regulations of Puerto Rico.

Visitors to Puerto Rico from foreign jurisdictions or U.S. jurisdictions where no medical cannabis identification is issued may apply for a Puerto Rican medical cannabis card after visiting an authorized healthcare provider. If the applicant qualifies as a medical cannabis patient, the applicant’s medical cannabis card will be valid for a maximum duration of 30 days.

The act of smoking cannabis is strictly forbidden, even for medical patients, and while other inhalable products are available, vaporizing cannabis flowers (buds) is only authorized if the patient’s healthcare provider has determined that vaporization is the ideal method of administration, if the healthcare provider has determined that no other suitable alternatives or adequate treatments exist, or if the patient has been diagnosed with a terminal illness. Dispensaries are prohibited from supplying cannabis flowers to any patient whose medical cannabis recommendation does not explicitly authorize vaporization of cannabis floral material.

It is unclear as to whether non-resident patients would be able to obtain cannabis flowers without first obtaining a Puerto Rican medical cannabis card. Non-resident patients who are unwilling or unable to obtain a Puerto Rican medical cannabis card and who rely on access to cannabis flowers are advised to obtain a note to that effect from their healthcare provider to present to dispensary staff along with a copy of their medical cannabis recommendation and home-jurisdiction medical cannabis card in case the note would constitute sufficient documentation for the dispensing of cannabis flowers.

Puerto Rico defines one ounce of cannabis flower as being equivalent to eight grams of THC in concentrate form or 800 milligrams of THC in edible products.

  • Resident Patient Possession Limit: 30-day supply
  • Resident Patient Purchase Limit: 1 oz of cannabis flower or its equivalent per day
  • Visiting Patient Possession Limit: 30-day supply
  • Visiting Patient Purchase Limit: 1 oz of cannabis flower or its equivalent per day

Rhode Island

Medical cannabis cards (or their equivalents) issued under the laws of other U.S. jurisdictions have the same force and effect as medical cannabis cards issued by the Rhode Island Department of Health. Therefore, visiting medical cannabis patients from elsewhere in the United States may access Rhode Island’s compassion centers (dispensaries) with their home-jurisdiction medical cannabis cards and another form of photo ID. Out-of-state patients will be required to complete a compassion center intake form to be entered into the compassion center’s tracking system.

  • Resident Patient Possession Limit: 2.5 oz of dried usable cannabis, 12.5 oz of wet cannabis, 12 mature cannabis plants, and 12 cannabis seedlings (personal cultivation is permitted when the patient or caregiver obtains a Plant Tag Certificate from the Department of Business Regulation)
  • Resident Patient Purchase Limit: 2.5 oz of usable cannabis or its equivalent during a 15-day period
  • Visiting Patient Possession Limit: 2.5 oz of dried usable cannabis, 12.5 oz of wet cannabis, 12 mature cannabis plants, and 12 cannabis seedlings (personal cultivation is permitted when the patient or caregiver obtains a Plant Tag Certificate from the Department of Business Regulation)
