This movie, despite it's surrealist title, has nothing to do with LSD.
It is an lesbian erotic film masquerading as an anti-drug propaganda piece. I say it is explicitly a lesbian one because when I skipped through 23 minute long sex scene, almost all of it was the main character (Alice) with another woman on a bed. Unless there were 10 second long straight scenes, I clearly hit the mark on what this film is.
All the story is told in the first 3 minutes and the last 18 minutes of the film.
I watched part of one of each of the scenes. The straight ones are unbearably terrible, with a clearly added-over moaning sound. The female lays on the ground moving her head back and forth, and almost all of it is a close up of her face.
The lesbian ones are very passionate, in fact, far too passionate. The actresses cling onto, kiss, and embrace each other in such a way that it makes me think that they enjoyed it. These are (from what I watched) treated more seriously, with energetic music placed over it, as well as the actresses (as mentioned before) embracing each other in a romantic, rather than purely sexual way.
