It&#x27;s not hard at all to find these drugs today, despite them being banned. I doubt a slight increase in DUI (which I don&#x27;t think would be born out) would outweigh pulling the rug from underneath organized crime in all of the Americas. Alcohol is a hard drug, despite being legal, and causes a lot more violent and destructive behavior than pretty much all illegal drugs.<p>The vast majority of people don&#x27;t do heroin because it&#x27;s bad for you, not because it&#x27;s illegal.<p>Could organized crime find other markets? Definitely. But no illegal market compares in size to the drug market, particularly the US drug market. Guns are already legal, kidnapping and extortion are much riskier and less repeatable, the explosives market is small and gets the national security establishment on your case.
