Among the many anti-marijuana films made over the years, it is generally agreed that the most famous of them all is Reefer Madness (1936), which earned a huge cult following in the 1960s due to its outrageously over-the-top depiction of marijuana use and its effects. Most of the anti-pot movies were false, exaggerated presentations of how the herb turned users into addicts and rivaled heroin as a gateway into sin, debauchery, violence and death. The U.S. was not alone in turning out these anti-drug scare films and one of the lesser known but historically significant releases for its time was Marihuana (U.S. title, The Marihuana Story, 1950), directed by Argentinian filmmaker Leon Klimovsky, who would later relocate to Spain and specialize in horror movies, spaghetti westerns and other low-budget genre efforts.
