A tax on over-the-counter diet pills could be an effective public-health strategy to discourage teenagers from purchasing the dangerous and 鈥渦seless junk,鈥� according to a first-of-its-kind study coauthored by economics professor Nathan Tefft.

The $66 billion diet industry faces few regulations, explain Tefft and co-author S. Bryn Austin in their blog post for . Yet 鈥渨hat the diet industry does not want you to know…is that most of what they sell is at best useless junk 鈥� and that could not be truer than for diet pills,鈥� say the researchers.

Weight-loss products are particularly dangerous, with 23,000 annual emergency room visits . Among girls and women, fully a third of these ER visits are caused by weight-loss supplements 鈥� yet teenagers, especially, should.

So what measures can policymakers take to keep diet pills out of the hands of teens? Based on the fact that taxes on cigarettes have been 鈥渙ne of the most effective strategies to date to drive down teen smoking,鈥� the researchers looked at whether 鈥渢axing diet pills might be a solution.鈥�

The answer is a resounding 鈥測es.鈥� A 20 percent tax on diet pills could lead to a 5.2 percent decrease in overall purchases 鈥� and, importantly, a 17.5 percent decrease among households with teenagers.

鈥淭hat may not sound like a lot,鈥� wrote Austin and Tefft, 鈥渂ut there are over 126 million households in the U.S., and roughly one in five of them purchase these products, so a 5 percent decrease across millions of American households is a lot of diet pills not finding their way into the medicine cabinets in people鈥檚 homes.鈥�

The study will be published in a

Tefft, who studies the economics of public health issues and has examined the effects of taxation on other products, conducted the study in collaboration with Austin, director of the Strategic Training Initiative to Prevent Eating Disorders at Harvard鈥檚 T.H. Chan School of Public Health and Boston Children鈥檚 Hospital; and with Selena Hua Liu of the Department of Nutrition at Simmons College.
