The Democratic-led Assembly on Wednesday backed legislation that would apply electronic cigarettes to the Clean Indoor Air Act.

The measure has been approved previously in the chamber, but comes as the Republican-controlled Senate is also considering the bill after it was approved last month by the Health Committee.

“While the state’s highly popular Clean Indoor Air Act has successfully reduced New Yorkers’ exposure to the dangers of second-hand tobacco smoke for more than a decade, the act unfortunately does not include the public use of electronic cigarettes,” said Speaker Carl Heastie. “Under this legislation, electronic cigarettes will be subjected to the same restrictions on public use that are currently applied to smoking tobacco in order to protect the public from being exposed to e-cigarette vapors of which there are serious conerns about their impact on human health.”

The bill would prohibit the use of e-cigarettes in indoor spaces that range from schools, workplaces, bars and restaurants. E-cigarettes could still be used in outdoor restaurants and seating areas were the current law allows tobacco smoking to occur.

Violations range from $1,000 to $2,000.

“We know that e-cigarettes emit vapor laced with nicotine, a highly addictive drug, volatile organic compounds, such as benzene, as well as heavy metals, including nickel, lead and tin, and the companies selling these products are using the same successful marketing strategies the tobacco companies used decades ago to get young people hooked on cigarettes,” said Assemblywoman Linda Rosenthal, the bill’s sponsor.

“This legislation is important because it will shield the public from being forced to breathe the dangerous vapor of an e-cigarette, and send the message to minors that e-cigarette usage could lead to a nicotine addiction and a lifetime of costly and debilitating health problems. It also will ensure the reasonable and popular clean indoor air standards that we fought to establish through the 2003 Clean Indoor Air Act are not jeopardized.”

Lawmakers this session also considering a bill that would raise the state’s tobacco purchasing age to 21.
