I just finished watching Paul Morrissey's Trash and I gota say that of all the drug film's I have seen this one seemed the most authentic. Not being a junkie I don't know what the lifestyle is first hand, and I was wondering if this film captures it?

Keeping in mind it was made in the 70's of course...

Yeah probably, considering the fact that all those Factory people were junkies (and/or speedfreaks) in real life. All except for King Warhol himself who would only take small doses of benzedrine to help him concentrate on his stupid silkscreen portraits of pop culture icons. Heil Valerie Solanas!

Yeah, that is true.
Come to think about it the scenes where he is shooting up are probably not fake either.
