Americans who are trying to kick their nasty smoking habit have found healthier alternatives in e-cigarettes and vapor products that could, quite literally, save their lives. But the bureaucrats at the Food and Drug Administration are trying to put this $3.5 billion industry out of business.

Small mom-and-pop shops have sprung up across the country to meet the growing demand for vapor products, which allow users to refill their vaporizers with their favorite e-juices. Separately, big tobacco companies have invested in non-refillable e-cigarettes.

Though these products are not always tobacco-free; there’s no ash or smoke involved. But they do contain nicotine, which users can gradually reduce if they choose. E-cigarettes and vapor products contain far fewer chemicals and carcinogens than traditional tobacco cigarettes, making them safer for the users, as well as those around them. “[T]he levels of potentially problematic substances in e-cigarette aerosol,” Reason’s Jacob Sullum wrote in March, “are about the same as those detected in ambient air.”
