I hate drug conversations, because so much misinformation and "personal experience in dealing with some guy i knew who told me about a guy that told him about someone" gets thrown around.
If you haven't spent time around pot smokers, or drug users, and you haven't done a controlled study, and ou have no reliable source that isn't a govt. funded anti-drug website, or other biased group... you really don't have much credibility. The same goes for the pro-drug side. If you are a junkie, and you can't live without your fix... then gtfo.
Now, people who are functioning members of society, who have used drugs in moderation, can pass them up when it isn't appropriate to use them (inb4 its never appropriate because it is illegal) and have witnessed their effects... then come on, sit down, and we can have a talk.
Personally, from what i have witnessed as an on again off again (now off for the last couple years) pot smoker, and hanging aroudn with a group of people who have smoked since forever... i can say with as much credibility as anyone ehre, that the people you would expect to abuse other drugs did, but the majority stuck to drinking and smoking a bit of weed. Now, i will be the first to admit, none of them are a great value to society, and none of them could ever e accused of changing the world... but they aren't on welfare, are employed (barring economic reasons beyond their control) and are decent people. No cocaine, heroin, crack, meth. Some vicodin abuse (i blame doctors being fucking tools partially)
That is my piece on marijuana. It isn't for everyone, but it certainly isnt for no one.
