Albany lawmakers are considering enacting the first ban on electronic cigarettes.
The plastic substitutes, called "e-cigarettes" do not carry warning labels, are legal for sale to children, and are heavily advertised on the Internet.
Manufacturers claim the devices are safe, emit only vapor, and can help people quit smoking.
Public health organizations say "e-cigarettes" should be regulated, like nicotine gum or patches, and warn they contain dangerous chemicals.
Manhattan Assemblywoman Linda Rosenthal, who introduced the legislation, says a study needs to be done on the health effects of "e-cigarettes" before sales are allowed to continue.
Her concerns center on the nicotine in the plastic devices and that most are made in China and other countries where product safety isn't well regulated.
