There are several aspects to this omnibus bill, all of which reflect aspects of reform that federal legislators can no longer ignore. Per Hermes, the CARERS Act is long overdue.

"Federal legislators are finally harmonizing their approach to widespread political will for medical marijuana reform in the US."

According to Marc Ross, an attorney at Sichenzia Ross Friedman Ference LLP, "Most importantly, it will take the government out of the doctor/patient relationship."

The change in the scheduling of marijuana will have huge downstream impact on many issues tied up in legalization. According to West, the move to Schedule II does open up additional avenues for federal research into the medical benefits of marijuana.

"The reasons by legislators to focus on the Controlled Substances Act (CSA) reflects the way in which the executive branch has addressed our country's drug policies for more than 40 years," she said. "The so-called War on Drugs has been waged almost entirely based on enforcement strategies and practices outlined in the CSA."

The methods of reform arguably begin with the CSA,  she said, including the reclassification of marijuana for medical use. That said, the legislation does address policy outside of the CSA. For example, the provisions addressing Veteran Affairs and banking protocol lie in different areas of federal law.
