Baltimore residents can now help health officials to work on the life-changing problem of tobacco use with a simple phone call.  Today, Mayor Stephanie Rawlings-Blake and Health Commissioner Dr. Leana Wen announced a new tool in the fight against sales of tobacco to underage youth. Individuals can now call 311 to report businesses that are selling tobacco to youth under age 18, and Health Department officials will investigate each complaint.  The Health Department has launched a public education campaign, with messaging inside buses and radio advertisements encouraging individuals to call 311.
