The California State Senate on Thursday passed a bill to regulate electronic cigarettes as tobacco products, sending the measure to the Assembly where a similar bill died earlier this year. The measure was one of several anti-tobacco bills that advanced in the Senate on Thursday, including one to raise the legal age for buying cigarettes to 21 from 18. The e-cigarette regulations, introduced by State Senator Mark Leno, a Democrat from San Francisco, would ban use of the devices, also known as vapor cigarettes or vapes, in the workplace, at schools and other places where cigarettes already are forbidden, and would require that they be sold in child-resistant packaging.
