I really can't think of a show considered to be the smokiest. There was a lot of herb being puffed outside after the De La Soul show though. It was funny, some audience member handed a blunt to Mase (De La DJ) and Butta Verses, and they all smoked it outside the bus together. Talk about connecting with your fans.
Sorry to SIr HC for getting burned and what not. I am a smoker, but realize smokers get a bad rap because of assholes who don't do it responsibly. I think doing it respectfully and responsibly would go a long way in easing the divide between smokers and non. I always exhale upwards and keep my cigarette in front of me when standing still near the railing. I don't smoke while moving. I think if others did this, it would be so much better.
And it should be up to the owner to decide to allow smoking or not in their establishments.
