Hello!

I am looking for a movie about a guy addicted to various hallucinatory drugs.
The most characteristic scene of the movie is when this guy goes to a female prostitute (I think she is a prostitute), she opens the door naked and as the camera moves down her body, she has a penis.
I also think that there are ants somewhere, either in the movie title or the guy sees them because he is under drug influence.
The movie is coloured, released not later than 2007 (somewhere in between late '90s or early '00s) and not produced by a famous company (no famous actor or actress in the cast, as far as I can remember).

My memory is lame and I can't think of any other details, unfortunately.

Thank you in advance :-)

It might be Naked Lunch, check it out on IMBD and see if it's the same movie.

I'll check it out.

Thank you very much!
