“The pursuit of happiness” is not defined in the Constitution. In fact, those words are not even in the Constitution, they are in the Declaration of Independence. Happiness is not guaranteed by the government, nor should it be. It’s far too vague a standard and the expense needed to fulfill it would be unimaginable. The idea that legalizing drugs would lessen the crime associated with drug use sounds nice, but I fear that those people making huge sums of money from their sale and distribution would not just give up the business. And that creates it own set of problems. Plus, while most drug users tend to be non-violent, far too many become aggressive and/or completely unpredictable and would still act this way whether they get their drugs legally or not. As with most problems in the US, I think the proper answer to the drug problem is somewhere in the middle. I do not agree with the “legalize everything and the trouble will go away” crowd, nor do I think that stuffing every Tom, Dick, or Harry caught with small amounts of drugs intended for personal use in prison for extended stays is a good idea either.
