All i can remember is a scene.
Its young character ( age 25 -35)
He breaks 4th wall.
He is at a party where people are sitting on the couch and some standing. He then talks to us viewer about what drugs they use and how they use it and how to share it.
Almost as wall of wall street acting but here it is about different drugs.
Movies is before 2013 and not older than 1980
I vaguely remember seeing something similar.
Was it Blow (2001)? : https://m.imdb.com/title/tt0221027/?ref_=nv_sr_srsg_0
Or Spun? (2002) : https://m.imdb.com/title/tt0283003/?ref_=fn_al_tt_0
*EDIT/UPDATE* : I just remember this movie from 2013: The Wolf of Wall Street https://www.imdb.com/title/tt0993846/?ref_=ext_shr_lnk
