Marijuana's Different Path
Marijuana has a somewhat different history of restriction in the United States than do opiates and cocaine. It was prohibited later, at the federal level. There has been more debate about its status, with some advocating decriminalization or legalization, while others found it as dangerous as the most restricted drugs. Since the 1990s, Americans have increasingly supported medical and even recreational marijuana use, although marijuana remains prohibited under federal law.
