“Marijuana is safer than alcohol, so marijuana should be treated like alcohol” is a catchy, often-used argument in the legalization debate. But this assumes that America’s alcohol policy is something worth modeling. In fact, because alcohol and cigarettes are used at such a high rate due to their wide availability, the country’s two legal intoxicants cause more harm, are the cause of more arrests, and kill more people than all illegal drugs combined. Alcohol happens to be legal for cultural reasons, and it would be difficult to turn back the clock on its legalization. But why add a third drug to the list of legal killers?
