When I played my first show...we wrote the songs together baked, practised together baked, and did the show baked...and it turned out BRILLIANT. Afterwards a group invited us to a party to play for them...and we got baked in the bathroom, but we did not perform baked there because we got kicked out!. The guy was on probation and just flipped! So I say, smoke out - as mentioned the whole band - but if you invited to an after party...smoke out only as allowed!!!

Good luck!!!
