I watched it trippin'

For years I was trying to remember the movie that I saw at a theatre in 1972 after I took LSD for the first time. I finally realized it was this movie. I took the tablet with a friend of mine then ended up at a theatre watching this movie. For years I was trying to find this movie because I didn't know if I really saw the movie or imagined it. I would love to rent or buy this to watch it again......this time straight.
