Don’t do drugs. Never has this simple message been made more effective than with the 1969 film Case Study: LSD. The film not only reminds us of why drugs are bad — it warns of the dangers of mixing psychedelics with tubed meat. And why ketchup on hot dogs is just plain wrong.

Warning: This video contains excessive use of Capri pants, and a dramatization of troll murder.
