There's pretty much nothing in this category.

There is one notable scene where several murdered people are laying down on the floor. Lots of blood is shown here, mostly around the bodies. However, this is the only major scene in this category.

Use of some bad words, like ass/badass, maybe damn, piss, or bastard, but nothing major.

The main plot is very focused around drugs.

There is are a few scenes some viewers could find frightening.
