Although marijuana has been fully legalized for recreational use in Colorado and Washington state, and legalized for medicinal use in over a dozen others, the federal government still categorizes it as a Schedule 1 Narcotic. That places marijuana among the most heavily restricted substances, alongside heroin, ecstasy, and LSD — drugs that are considered by the government to have no medical value and a high potential for abuse. Marijuana was added to this group in 1970, but drug reform advocates have been calling for its removal to a lesser category (there are 5 categories of controlled substances maintained by the DEA, with 5th being the loosest in terms of regulation) ever since then.
