Flavorful Highs

Jacob Sullum defends them:

Although flavored e-cigarettes and marijuana edibles are intended for adults, appeal to adults, and can be legally sold only to adults, the prohibitionists argue that they cannot be tolerated because they also appeal to minors. The same rationale has been offered for bans on flavored tobacco products and sweet malt beverages. This argument, although couched in the language of moderate and sensible regulation, should be a non-starter in a free society, because it reduces adults to the level of children.

And flavored e-cigs make quitting real cigarettes easier:

Two-thirds of the ex-smokers in the E-Cigarette Forum survey said nontobacco flavors were important in helping them quit. Survey data reported in the International Journal of Environmental Research and Public Health last December likewise indicate that flavor variety is important in quitting. That study, which involved about 4,500 vapers, found that they tended to prefer tobacco-flavored fluid initially but later switched to other flavors. Most reported using more than one flavor on a daily basis and said the variety made the experience more interesting and enjoyable.
