Why Is Marijuana A Schedule I Drug?

Amy Nordrum, International Business News

The U.S. Drug Enforcement Administration lists marijuana in the most restrictive of five classes that the agency uses to regulate dangerous drugs. Marijuana is classified as a Schedule I substance, which is the ranking reserved for drugs with the greatest potential for abuse and with no medicinal value. Heroin, ecstasy and LSD are listed in that category, too, while cocaine and methamphetamine rank one level lower than marijuana, as Schedule II.
