County Supervisors have passed a measure that prohibits the use of electronic smoking devices in places where tobacco smoking is banned, including in public buildings in unincorporated areas and county parks. 

The battery-operated electronic cigarettes vaporize nicotine in a liquid solution, and the smoker inhales vapor rather than tar and other harmful compounds in tobacco.

Supervisor Ron Roberts stressed that the regulations would not put electronic smoking devices out of business, but would only limit where they could be used. "If people want to use it to stop smoking, God bless them, but they're just not going to be able to do it everywhere," Roberts said.
