; propylene glycol and vegetable glycerin are designated as generally recognized as safe by the Food and Drug Administration (FDA) as food additives. (7) Surveys have found that a significant majority of regular users of electronic vapor products had previously tried FDA-approved smoking cessation drugs to quit smoking without success. (8) An expert independent evidence review published by Public Health England (PHE) concluded that— (A) the use of vapor products is about 95 percent less harmful than cigarette smoking; (B) nearly half the population doesn’t realize vapor is much less harmful than smoking; and (C) there is no evidence suggesting electronic vapor products act as a route into smoking for children or nonsmokers. (9) Electronic vapor product sales in the United States have increased from an estimated $100 million in 2010 to $4 billion in 2016 while cigarette consumption in the United States declined from $307 billion in 2010 to an estimated $265 billion in 2016. (10) On May 10, 2016, the Food and Drug Administration issued its Deeming Regulation to deem e-cigarettes or electronic vapor products to be subject to its authority. The regulation will, as a practical matter, because of its significant compliance costs and poorly articulated standard for protecting public health, ban the sale of all electronic vapor products by August 2018. (11) The Food and Drug Administration’s Deeming Regulation, by effectively banning electronic vapor products, will push vapers who have quit or reduced cigarette smoking by switching to electronic vapor products back to smoking deadly cigarettes. (12) The 2015 Monitoring the Future survey of the National Institute on Drug Abuse found past-30-day use of an electronic vapor product by 8th, 10th, and 12th graders combined declined from 13.9 percent in 2014 to 9.9 percent in 2016
