Agreed--I'd argue that a physically harmless, pleasure causing, addictive product is inherently worth of regulation. Dependence (use without truly wanting to) and abuse (use despite harm--which can arguably include financial harm even with no physiological affects) are the criteria for a substance use disorder which is in itself a medical diagnosis. Products that serve no useful purpose and readily lead to the development of use disorders should not be sold.
