As someone who NEVER used pot, I noticed as I went through the 60s and 70s and 80s, that those who even used harder drugs seemed to keep quick intelligence (somewhat), but those who heavily used pot, just went to DUH!!!!!!!!!!!!!!!!!! I think it was encapsulated in a conversation my brother had with one of our fast friends who was growing pot in one of his stereo speakers (so his mom would not see it). "Say Brian, how many joints (they were called joints not blunts back in the day) do you smoke a day?" "Oh about one a day." "So how many do you smoke a week?" "Oh about 10." My brother laughed, but there's nothing funny really about it. Didn't occur to Brian what was funny. In the book "Boy Clinton," the author postulated that the reason liberals, especially the 60s hippy generation never learned from their mistakes is because they couldn't. All those years of drug use had rendered their brains encapable of learning from their mistakes and failures. I also noticed that people like Clinton and Hillary had the emotional maturity of teenagers. The "I didn't inhale" president most certainly did. Cannabis smoking 'permanently lowers IQ' - Telegraph Now, this is going to JUST send the pot users into conniption fits. Mostly because all addicts refuse to accept they can't handle their addiction. It's part of the ego and pride. (And yes, I mean addiction. Pot raises the serotonin in your brain, and it falls later, and you get depressed (the crash). It gets to the point you can't feel happy without the pot. That's an addiction. Yes it is.) Don't believe me? Look at every drunk driver video. No matter how obviously impaired they are, they refuse to believe they can't drive. It's a matter of ego and pride. No, different with pot users. They are emotional to the point of not being able to discuss the subject objectively. How do I know? Because of the STUPID argumements they use to justify their use. "How would you know how pot affects you? You've never used it." To which I've always responded: "I don't have to jump off the cliff to know it's a stupid thing to do, I just watch the other moron do it, to know it's a stupid thing to do." "Well what about alcohol??? How come it's legal?" To which I respond: "What of it? Are you suggesting getting drunk on alcohol vs. pot is better or worse? Maybe that's why there are some of us who don't do either." Then there is the really ludicrous argument. "Well, I can smoke pot and drive where I couldn't on alcohol." Yeah, well the drunk driver thinks he's fine to drive, too!" Then there is the "medical marijuana" argument. Which amounts to pot heads hiding behind the sick and dying to justify getting stoned. Which I would liken to a morphine user justifying morphine based on the fact my dying father was prescribed it, when he was dying of cancer, for his pain. NOT the same thing people. It's still hiding behind the sick and dying to justify getting stoned. Is anyone going to tell me morphine is "beneficial?" But pot is? And if you even question this, you are "hard hearted" because of the sick and dying, when most "medical marijuana" users are perfectly fine, and will use any excuse possible to justify getting the pot. Now let the tirade of of outraged pot heads begin. They have something in common with libs. They know if people factually discuss the issue, they lose. So, they HAVE to hide behind the sick and dying, to shut up any real discussion as "hard heated." Which is what you do when you know the facts aren't on your side. You shut up any discussion of the facts.
