If that effort succeeds -- if the FDA mandates "nicotine-free cigarettes," for example -- the inevitable outcome will be a flourishing black market. Tobacco will become the new "forbidden fruit" as criminal gangs hook underage smokers on an adulterated product freed of all constraints on quality that competitive markets normally afford. Neither the FDA nor even the U.S. Congress should be entrusted to make basic consumer choices for individuals. At most, government might disseminate information on product safety and efficacy (although private companies could do that job better). That leaves individuals free to make their own decisions.
