Umm, how does making the fruit forbidden make drug addictions go away? You assume that making drugs legal would be associated with a statistical increase in the number of drug addicts. However, if you actually got off your ass and did your homework, you'd find that drug use goes up when drugs are outlawed! Making the fruit forbidden makes it more tempting.

Throwing drug users in prisons is not as effective as actually treating them like human beings and helping them with their problem. In fact, throwing drug users in prison with a bunch of violent criminals just makes them really violent and angry, which means they're more likely to shoot you when they get back on the streets!

When you make drugs illegal, you don't get rid of them. You just confine them to a black market, where the only way to resolve conflicts is violence. That's why drug users are so often violent criminals. Because they're involved with a black market out of necessity.
