A press conference at city hall Monday is the first salvo in a huge campaign to outlaw smoking just about everywhere in Dallas where it isn’t already outlawed, including bars and taverns — almost the only places left where a smoker can smoke within the city limits, according to the DMN. Monday’s press conference is being hosted by a group of heavy-hitters against smoking, including the American Cancer Society, UT Southwestern and the American Heart Association. Mayor Tom Leppert and councilman Ron Natinsky already are on-record as supporting the full-fledged ban, which will probably be acted on in August when the council returns from its summer break.
