Great suggestions!

I would add:

1. The original Mortal Kombat movie from 1995. B-Movie camp at its finest!

2. Anything with Jim Carrey (comedy or drama) but The Mask is probably the funniest and trippiest. Or Ace Ventura. And The Truman Show will have you going "woah man, what if?" to your friends afterwards. Try watching "Jim and Andy: The Great Beyond" if your taste is more spiritual/philosophical. In fact the only JC movie that I would say definitely does NOT go well with drugs is "The Number 23" as it could make you paranoid in a bad way.

3. Currently showing in cinemas: Everything Everywhere All At Once - one of the most insane and amazing movies I've ever seen. Saw it once high and once sober, both times incredible.
