Paul Armentano makes it, at length. One leg of his argument:
Several objective bodies have sought to assess the potential costs that marijuana use may impose on modern society. These calculations have consistently estimated the social costs associated with marijuana’s use to be relatively minimal. For example, a 2009 assessment published in the British Columbia Mental Health and Addictions Journal estimated that health-related costs per user are eight times higher for drinkers of alcoholic beverages than they are for those who use cannabis, and are more than 40 times higher for tobacco smokers.[11] “In terms of [health-related] costs per user: tobacco-related health costs are over $800 per user, alcohol-related health costs are much lower at $165 per user, and cannabis-related health costs are the lowest at $20 per user,” investigators concluded.
