Bennett Minton [letters, Jan. 15] noted that lighting a marijuana “nightcap” causes harm to “collateral victims” through the “violence and waste” that result. But choosing an alcoholic nightcap also causes collateral damage by funding violent mobsters such as Al Capone. Oh, wait — that was only true during Prohibition. So maybe it’s the drug law, not the drug, that causes most of the collateral harm.
