Canadian health officials are warning Charlie Sheen not to smoke when he takes the stage during the Toronto stop of his "My Violent Torpedo of Truth" tour.
Sheen, who has frequently puffed on a cigarette onstage during earlier tour stops, will perform his one man show at Massey Hall for two nights starting Thursday.
Ontario Health Promotion Minister Margarett Best said health inspectors would be watching to ensure Sheen didn't light up onstage.
Sheen's recent erratic behavior and battles with "Two and a Half Men" producer Chuck Lorre prompted Warner Bros. Television to fire him from the top-rated sitcom.
He's since filed a $100 million lawsuit against Warner Bros. and Lorre.
