Intended as an anti-drug propaganda film, Doped Youth (also known as Reefer Madness) ended up becoming a bit of an exploitation film. It deals with a group of young people whose lives are torn apart by marijuana. The film is also utterly awful.
Mae (Thelma White) and Jack (Carleton Young) are a couple (unmarried, tut tut) who get High School kids to smoke some pot. This does not end well, in fact it ends up with a number of deaths.
All the ingredients are here for 1930s moral panic in America: drugs, jazz music and dancing too close. The effects of pot are somewhat exaggerated. According to this film it leads to violence, death and insanity. After watching this low-budget nonsense it might drive anyone to substance abuse to be honest.
