I have seen a lot of movies based off drugs and most of them were trippy, but I have found an awesome film called "Enter the Void" that might beat it all to the top. From opening credits to visuals to the ending it is a 100% trip. There are use of DMT drugs and hallucinations which is insane when your stoned. Not only that but the way the film is shot and the grisly atmosphere tops it off. I recommend yall blades to check this film out.
