And pot smokers will argue and defend this to their death because of the power of their dependance upon it - which they claim is non existent.
I love this. If I try to defend my pot use, I'm admitting a dependence I don't have.

Nice way to win the argument every time Joe Nerve.
This.
And I'd like to add 'unintelligent' to the mix. Witness a (musician) friend of mine who believes his bipolar and anxiety disorders have nothing to do with the copious amounts of pot he smokes - which presented themselves, oh I don't know, about a week after he began doing drugs.

So, is he doing drugs, or just pot?
I may be young, but in my opinion, just because someone drinks beer or smokes pot, it doesn't make them a weak minded failure as a person. Yes they do alter your perceptions but that doesn't mean they necesarily change you. Saying you can't have a conversation with a person who is high is not due to the drug, it's due to the person taking the drug. I used to smoke a ton of pot but I don't anymore. That doesn't mean that all my friends don't. I would say that they're the exact same person stoned as they are sober, just a lot more mellowed out.
if someone has a problem, don't blame the drug, blame the person. You're just immediately writing off plenty of people who can do it and still be a functional human being.
THIS sounds like the stoners I know. I've never run into one of these horribly dysfunctional pothead stereotypes that others seem to have encountered. I hang out with and smoke, on a near daily basis, with a girl who is a lifeguard, substitute teacher, and going to college to teach physical education. Another friend, who smokes like a champ, has a steady job at Borders and is going to school to be an English teacher.
My mom has started smoking it to help with her back pain and arthritis after my very knowledgeable sub/lifeguard friend informed her that marijuana is a natural anti-inflammatory. She doesn't get around too well that much anymore and is in pain most of the time. She said it helps her as much as any vicodin or oxy pill does. At least pot she can't get physically addicted to. My dad who is trying to quit his lifelong addiction to alcohol (hello legal substance far more harmful than pot) smoked pot to help with the anxiety and restlessness of alcohol withdrawal. When he's stressed out, he'll take a couple hits instead of thinking about going and buying a bottle of vodka.
What does all this have to do with the topic at hand, musicians getting hooked on drugs? It's not just musicians using drugs, it's everyone in every part of our society. Teachers, lawyers, doctors, the kid running the car wash or the one serving your food. Musicians definitely tend to flaunt it though. For hells sake, I play in a genre of music labeled "stoner rock". It's almost guaranteed when my band or any band in this genre, plays a show that there will be weed at the show, from us, or the other bands or from someone in the crowd. It's a horribly cheesy thing, and as serious as I take the music and our live show, you can't help but laugh at it. Maybe laugh WITH it is more appropriate.

But in my experience, musicians tend to be more open about their beliefs and I think that's true of any type of artist really. So a musician that happens to do drugs isn't likely to hide that fact so much as most everyday folks. It doesn't help that whenever a musician dies of drug use, or abuse, the media devotes nearly a week to talking about it. But what most don't realize, is that while you're watching the three day long news report about that dead celeb, your neighbor could be smoking some weed, doing a line of coke off their kitchen table, or whatever their drug of choice, and chances are, you'd never know and probably never will. But it is everywhere. We don't see it BECAUSE of the laws in our country and most people in mainstream society obey the law without question. Free thinkers, which musicians stereotypically are, are a lot more likely to be the ones questioning authority...
And the only reason I'm keeping the focus of this on pot, is because if your neighbor is really doing any drugs without your knowledge like in my hypothetical, it's likely to be pot, and I'm betting on it that everyone will be seeing it a lot more. I've only smoked for two years and in that two years, a lot of things have changed in terms of law enforcement cracking down on pot, because people are finally realizing now that it's not the demon drug Harry Anslinger made it out to be in the 1930's and that it's a huge waste of money trying to keep fighting the war on weed. Cops realize it's a waste of time and money. In Chicago, no one seems too afraid anymore to just hang out on the street and smoke a joint, because, unless someone else complains, the cops aren't likely to do anything about it as they have real problems to deal with, murder and hard drugs. I think the next ten years will be real interesting as far as prohibition goes.
Of course, the usual IMO, YMMV, IME, etc...
To the mods... sorry if I'm pushing it with this one in any way.
