Okay, I discussed with my mother about this and I'm still interested what other people think about that issue.

The leading questions (for those who don't want to read the whole post xD) are:
- Do people who are intelligent - above average - tend to do drugs?
- Shouldn't they be intelligent enough to know that this is bad (and that they can become addicted)?

These were the two questions I asked myself. I talked with my mother about it and funnily the first question CAN be true. At least we both know some people who do drugs.

A former friend of mine for example. He thought he was totally dumb all the time (at least he said so) until the day someone told him we was intelligent (above average). At least he says so. I can't quite believe that he really is intelligent. He just can't be.
As most people my mother and I know, he claimed he thought about the world a whole lot of time and thought that it was all bad. These persons mostly say that as they're so intelligent they can see the world as it really is: rotten, bad. So they get depressed over that thought - they don't see any way to change it.
Whereas the people who aren't scored "intelligent" think that they can change the world and make it a better place.
Besides, I think it's commonly known that handicaped people tend to be happy and think the world is a great place to be.

So those intelligent people all want to escape from this bad world. (Uh, wait, I'm getting sarcastic, sorry for that, I think I can't be neutral when it comes to drugs...) How? Easy: Drugs. They make them feel better and let them escape reality. (I haven't done drugs even ONCE so I can't say if this is what everyone feels. But I've heard from the "intelligent" person I mentioned above that he just did it to feel better and.. somehow compensate his inner pain.)

The one I mentioned isn't the only one I've heard about. A guy I liked also was claimed to be rather intelligent - he smoked weed. (No, not just "a bit each month", but each week and a whole lot!)
My mother told me about a girl she heard about who attended university when she was only 17/18, but now has gotten pregnant - and dropped her study.
Also, and that's why I even came up with that topic, I read some reports of school about my brother and his teacher in the first and second grade wrote that he was "very intelligent". I wouldn't say that my brother's that intelligent. He doesn't do drugs regularly, but he drinks a whole lot of alcohol each week and as far as I know he's done drugs when he was 17 or so. .-."

So I wondered about the second question: If you're so intelligent, shouldn't you know that you hurt your body through doing drugs? That you can get addicted? That this will cost you a lot of money?! That may be totally stupid of me, I know, but I just can't believe that people who do drugs are very intelligent. It's not that people who do drugs are dumb, either. It's just that intelligent people should know about the risks of drugs.

I just don't get this all. What have you experienced?
