Marihuana chronicles the downward spiral of a group of teenagers from frivolity into the depths of decadence brought on by smoking the "giggle weed." A young girl drowns while skinny-dipping at a beach party. Another teen gets pregnant after a turn with her boyfriend in the sand - both the result of dope smoking. The mother-to-be gives up her baby and becomes a hardened drug dealer, earning fur coats and diamond rings while coldly turning her clientele into drug addicts. With a central message that usingmarihuana incites "the user to extreme cruelty and license" and down the path to hard narcotics, this 1936 precursor to Reefer Madness is a cult classic by director/producer and exploitation master Dwain Esper. Contains nudity.
