drug with drug
Even if this just remains consensual, there are lots of possibilities here. Helping out your friend who's too exhausted to move, slinging single doses at parties, doing a line off a stripper...fighty people could even start bringing squires with them to dose them up mid-combat so they're not wasting actions on drugs. Teamwork! Would be a great use for ganger pledgies who can't fight good yet.
I'm sure this has been suggested before but I wanted a new thread for it!
