Smokers should be permitted access to inhaled cool nicotine mist products instead of cigarettes, in order to reduce the harms caused by inhaling hot tobacco smoke and the carcinogens it contains. This strategy admittedly does not reduce the harms caused by inhaling nicotine, but the authors state that “up to 98% of tobacco-related deaths are attributable to combustible products". E-cigarettes reduce exposure to hot tobacco smoke and its harms, while introducing possible unknown harms from the long-term inhalation of ingredients they contain, such as propylene glycol. There is a nicotine inhaler product (“Nicotrol”) which delivers a mist of cool nicotine absent the questionable ingredients found in e-cigarettes. Unfortunately, it is expensive and requires a prescription. I call for the FDA to consider permitting over-the-counter sale of nicotine mist inhalers, to allow them to compete more effectively with cigarettes and e-cigarettes.
