Should be illegal. The main problems with weed is addiction, dependence and the halt of critical thinking. It IS addictive, whether you go through physical withdrawal without it or not does not mean it ISN'T addictive. ALL potheads are mentally addicted, a few of my best friends say they aren't addicted, yet they spend money on it EVERYDAY and cannot go through daily life without it. Just because they aren't physically addicted doesn't mean they aren't mentally addicted. Not to mention it DOES have bad affects on a person. One of said friends has CVS, his doctor attributes his trigger to smoking, while he, suffering from weed addiction, says his doctor is wrong because the internet and his friends say weed has no harmful affects. Critical thinking power, zero. He continues to smoke daily and spend all of his money on it. But that ISN"T addiction?
The main problem behind it is the halt of critical thinking, not induced by the drug itself, but by the culture produced around said drug. Nothing negative can be mentioned about it, ever. Weed comes before all else. Oh it's just weed man, it doesn't do anything to you. It alters your brain. It makes you have zero ambition, it makes you spend hard earned money everyday. It get's you arrested. Why? To get high, the one and only reason. It's especially bad for the weak willed. Long story short, if you have to smoke everyday, you're addicted. I won't even get into the gateway drug part.
