Placer County has banned the use of electronic cigarettes within public buildings and inside county-owned vehicles.

Supervisors voted unanimously for the restrictions during a meeting Tuesday where nobody spoke about the issue during public comment. The ordinance will take effect in late April.

The use of electronic cigarettes, also known as “vaping,” has been touted by supporters as a safe alternative to traditional tobacco products such as cigarettes. But public health officials say the safety of the chemicals contained in e-cigarettes is unknown.

Kirk Uhler, chairman of the Board of Supervisors, says the ban goes toward making a comfortable work environment for public employees.

According to the Sacramento Bee, more than 150 jurisdictions in California have passed legislation regulating e-cigarettes.
