I think the world would be crazy if all drugs were legal. I thought up this scenario in my head it's like a science fiction movie:
There would be only two classes of people. Those who sold drugs and those who used them. The people who sold them wouldn't do drugs cuz everybody knows crackheads make lousy drugdealers. Since people do crazy shit to get drugs when they hooked the rich get richer and the poor stay poor. The drugdealers would then put the users in enviroments where the users children ran a higher risk of becoming addicted. This way there was always a need for the product. The users would be so busy killing each over drugs that they would never even think about revolution or ever realize who was really creating their problems. The eviroment the users stayed in is made to believe in lots of sex and illegitimate children are born everywhere this creates a constant buyers market and fresh new consumers. When there is too many users born a drug is made that is highly lethal and addictive to control the population. But when there are too many dealers born it creates chaos and war amongst the dealers cuz nobody is using the drugs and no money is made. So war ensues where a majority of everybody is wiped out except for a select group of dealers and enough controled users, for the dealers to start all over again. Or a super "user" is born that unites the rest of the "users" under a new/old law, and they rise up and wipe out all the dealers and the dealers way of living and start a new freeworld that is "user" free. That'd be a crazy world to live in huh?
