Regarding Thadeus Greenson and Grant Scott-Goforth's Nov. 13 column ("Legalized It"), the days when politicians can get away with confusing the drug war's tremendous collateral damage with a comparatively harmless plant are coming to an end. Marijuana prohibition is indefensible. If the goal of marijuana prohibition is to subsidize violent drug cartels and open a gateway to the hard drugs they sell, prohibition is a grand success. The drug war distorts supply and demand dynamics so that big money grows on little trees. If the goal is to deter use, marijuana prohibition is a catastrophic failure. The United States has almost double the rate of marijuana use as the Netherlands where marijuana has been legally available for decades. The criminalization of Americans who prefer marijuana to martinis has no basis in science. The war on marijuana consumers is a failed cultural inquisition, not an evidence-based public health campaign. It's time to stop the pointless arrests and instead tax legal marijuana.
