Marijuana is a [[Schedule I]] [[Controlled Substance]] in the United States of America, meaning that it is illegal under federal law of the United States,  and considered to have no redeemable medical value. According to the FBI, in 2012, there were 658,000 arrests for marijuana possession compared with 256,000 for cocaine, heroin and their derivatives.<ref name=nyt>{{cite news|url=http://www.nytimes.com/interactive/2014/07/27/opinion/sunday/high-time-marijuana-legalization.html?_r=0|title=Repeal Prohibition, Again|work=New York Times|date=July 26, 2014|accessdate=July 27, 2014}}</ref>

A few libertarian-leaning conservatives, most notably [[Ron Paul]], [[William F. Buckley]], and [[Larry Elder]], have advocated the decriminalization of this drug. Some [[liberal]]s support legalization, but most instead advocate for drug treatment and rehabilitation. [[Libertarian]]s are usually the biggest supporters of marijuana legalization. [[Gary Johnson]], a former Republican and 2012 Libertarian Party Presidential candidate for President, is the highest ranking US politician to advocate for marijuana legalization. He was a two-term Governor of [[New Mexico]].

Advocates of marijuana claim that the active ingredient in marijuana, [[Tetrahydrocannabinol|THC]], has been shown to produce some short-term psychological and medicinal "benefits", which are probably more than offset by the medical harm.
