Seriously, I would use that situation as an opportunity to ween of rec drug use, or to decrease the tolerance and use-level.
If all you're buddies are doing it, there's no real need to stop using. But if there's an outside force, like in a relationship that indirectly can put pressure to limit or stop the use, then that's an opportunity to do so.
Because as fun as it is, eventually there's a time to stop, and now is as good a time as any, even if it's just recreational.
I'm not saying this in a 'preachy' way, because I'm in the exact same boat.
