Minessota's 'theatre nights' bypass smoking bans

What do the names "Before the Ban" and "The Tobacco Monologues" have in common? They're both being used to describe themed theatre nights in Minessota bars - exploiting a loop hole in a smoking ban introduced last October that allows cigarettes to be puffed in thatrical productions.

Health departments and state authorities are not amused.
