My view on drugs is that marijuana at least should be legalized everywhere, and other drugs (Salvia, Cocaine, Heroin) should be judged on a case-by-case basis. Heroin should be stamped out completely because it fucks people up so bad. Same with crack cocaine and, to a certain extent, powder cocaine as well. LSD Acid causes horrible hallucinations and should be rigidly controlled, if not banned.
--Which should be legal and why?
Pot should definitely be legal, at least for those of majority age. My thought is that, since so many people use marijuana (many more than smoke tobacco), if the government legalizes it and then sells it through state stores (like they do with alchohol), then they a)can tax the shit out of it and get us out of this depression/recession within six months and b) control what is in the cannabis, make sure it's nothing but weed. The current ad campaign was started because some kids got ahold of some bad weed and died of it; the five-oh believe it was laced with morphine or some other, harder substance in an attempt to get the kids hooked and coming back for more. Or at least, that's the reason for the crackdown in my area.
--Why do you choose to use or not use them?
I have, on occasion, had a joint. I do so with my friends or, if I'm having a really bad day, I'll light up on my roof occasionally. I don't see anything wrong with doing so or with aomeone my age doing so. I understand that there are irresponsible members of my age group who use every drug known to man, and this is why there should be government control: you take a test to see if you are semi-responsible and then you get a card or something that says " has passed the ARDUE (Approved Recreational Drug Use Exam) and is allowed to carry: x grams of marijuana, y grams of nicotene, z grams of blah, blah, blah." Then, if the blue searches you, you show them this card and they are not allowed to prosecute unless you have more than the amount shown on the card. Simple and effective.
--Does your opinion of a person change if you find out they use drugs?
As several people have already stated, that depends on the drug. If someone is a hard crack cocaine user and is stoned out of their mind on a daily basis, then they are contributing less than nothing to society. If someone is smoking a bit of weed on a weekly basis and might be stoned one out of every ten times you go over to their house, that's not a problem. They're still accomplishing things when they aren't stoned. A crack addict's time between doses is entirely taken up with finding the next dose. Yet another reason for drug control.
There's also this picture I found:
Ok, I can't find it right now because I can't access Facebook from school, but I'll edit this post with it later. It's really frickin' funny.
