'LSD': Trip or Trap! (1967)

The Inglewood Police Department's 1960s video, "LSD: Trip or Trap?" is a classic of the genre. Alex sez, "It's a story of two friends who enjoy flying model planes, except that one becomes an 'acidhead' so he can be 'groovy' with the other acidheads. The other does research into LSD and decides it's a 'bummer'."
