I have the vague sense that pot wouldn’t even do anything for Peter, and that he just does it because he likes watching Chris smoke. Also probably because high!Chris is really entertaining or affectionate or horny.
See, and my theory has always been that pot is one of the things that would work on werewolves. Because it has fewer barriers to pass before impacting the system (as opposed to alcohol). Now, I think the high would dissipate pretty quickly once they stopped smoking, but as long as they took regular hits, they could get high as well as anyone.
Not that Peter doesn’t really like watching Chris smoke and/or get high.
