Electronic cigarettes don't burn anything and emit an odorless vapor instead of smoke, but users say they sometimes get treated as if they'd lit a reeking cigar. Use of the devices in places where cigarettes are banned has sparked fierce debate, and some states, cities, and workplaces have reworked smoking bans to include them, AP reports.
Anti-smoking groups want the devices covered under smoking bans until it can be proven that the vapor does no harm whatsoever. Users say anti-smoking groups should be on their side because the ability to use the devices in public is a powerful incentive for cigarette smokers to quit. "Not one cigarette in almost two years now," boasts one user who switched after 45 years of smoking. "How could you be against that?"
