They aren't worrying about us abusing it. If that was the reason it was illegal there are alot of drugs that these pharmaceutical companies make and they are well aware of the drug's addictiveness and side-effects but they continue to ship it out and make money from it. Why? Because they are pills that takes some type of lab to make, it's mostly a controlled type of substance and easier to monitor than marijuana. It's all about money, that's why it isn't legal. You could find a good area outdoors and not invest much at all and end up with a 200 plant field and make quadruple the amount of money selling it than you ever spent on the operation. Just one of the many reasons they hate it, but can't do shit about it. For every 100 busts they make there is another 10,000 they missed .
