Perhaps drug usage appears in the manga?

Spoiler for Black Lagoon OVA, Ep25 to 29:

Roberta was heavily dependent on steroids and probably a range of other performance-enhancing drugs throughout the OVA. She was literally consuming them like a child stuffing himself with candy.

^ What Sumeragi said. Drugs aren't just taboo, and anime isn't really the best medium to explore the serious topic of drug abuse.
