Prohibition didn't work for alcohol even though alcohol is known to be more distructive then any other drug. How does the government justify making certain drugs illegal? During Prohibition the consumption of alcohol was made more dangerous, because you had inexperienced people trying to make the alcohol and adding substances to it that would make it more dangerous to consume also people would have to buy it from bootleggers and back alleys making it more shady for transactions making it also more dangerous. So this is the case with those drugs which are illegal now. Many times drugs end up having toxins added to it making them far more dangerous then if they were legal and sold at a pharmacy. Because people are still going to get those drugs whether legal or not, but by making it illegal those people are being put into situations that actually cause the issues they are trying to prevent by making it illegal. So this becomes a self destructive loop where in so many ways making drugs illegal is society's cure to the problem which has become worse then the disease itself. I realize how abuse of drugs can be destructive, but by making it illegal it becomes even more distructive, so in the same way as we pick our president shouldn't the government atleast choose the lesser of the two evils by legalizing those drugs that they've criminalized because of course theres still going to be issues with drugs if legalized but there will be less destruction then the issues caused by making it illegal.
