None Really. Occasional very mild sexual references.

None at all.

About 20 uses of "fuck", a few "shits", "nigger" is used about 30 times throughout the film.

Alcohol is consumed and cigarettes are smoked at a party. Drugs are consumed briefly.

Nothing too intense. The ending of the movie is somewhat depressing. A scene where Lenny meets up with some childhood friends leads up to a dispute (non-violent) that is somewhat intense.
