A campy late 1950s anti-drug propaganda film starring Russ Tamblyn with Jackie Coogan (Uncle Fester from The Addams Family) playing a soda fountain owner/drug lord. It opens up with a sequence of Jerry Lee Lewis playing the title song, one of his all time best songs (The Killer was considered to represent the height of depravity at the time to mainstream America, hence his presence in the film). One could say it's more or less the dark side of "Happy Days" as clean cut American teenagers start smoking pot, listening to rock and blues, getting into juvenile delinquency and (implied, given the era) promiscuity, and eventually heroin. It's a lot more fun to watch than "Reefer Madness" not only because of Jerry Lee (and the whole idea of Uncle Fester getting kids hooked on pot and then moving them on to heroin) but because it is actually a pretty well made film in a 50s B way.
In the 70s people would go to midnight screenings of High School Confidential and get stoned.
