But why would people pay so much for a drug that causes a hallucination that they probably won't even be able to remember?
This seriously discredits your position in the argument as you obviously don't even realize that Marijuana isn't a hallucinogen, but a narcotic. It doesn't make you go "WOAAAAAH DUDE I CAN SEE RAINBOWS AND UNICORNS" at all, and by simply stating that it does is evidence enough that you simply do not belong in this argument.
Marijuana alters your attitude more than anything, but it also affects other senses (hearing and taste mostly, with a VERY positive affect). More often than not it will make you more receptive to humor, not because you simply find ANYTHING funny, but sometimes when I'm stoned and watch something that I may have seen before I'll catch something that I have never noticed before, it could be something someone said in the background, or a joke that your mind was perhaps a bit too "up-tight" or preoccupied to really understand the humor behind it when watching it sober. It does all this at the same time, and ultimately, more than anything, it makes you relax.
That's why the unemployed or depressed will sometimes turn to marijuana, because it simply helps them chill the fuck out and put their problems aside for a short while. Many people I know suffer from depression as I live in a relatively poor area, but when they're smoking, you'd never notice it, say what you want, but from observing these people over the last few years it is clear to me hat they definitely have lightened up and are now either reintegrated into society or on their way. That is why people want it so bad, if you were to completely remove it from these areas, you're making everyone constantly acknowledge that they are in fact poor and depressed.
