I can't say i have ever been able to smoke a bowl at work, maybe a 1 hitter, but a whole bowl would be a bit risky i think.
Back in the highschool days i would burn bowls in under 2 mins though, when i knew i had limited time. It was a damn terrible waste of bud though because i would have to just tourch all the damn greens at once and power chief as hard as i could.
