A new ad has appeared on the CBS SuperScreen in Times Square telling smokers they have a choice. National Vapers Club has furnished this ad and accompanying website in order to raise awareness about electronic cigarettes (e-cigarettes). e-cigarettes are battery-powered devices that vaporize a liquid -- similar to that found in fog machines --that sometimes contains nicotine. They are in danger of being banned in many jurisdictions across the country, including in New York.
