Cannabis Compound Said To "Halt Cancer" 383

h.ross.perot informs us of research out of the California Pacific Medical Center Research Institute suggesting that a compound found in cannabis may stop breast cancer from metastasizing. Cannabidiol, or CBD, could develop into a non-toxic alternative to chemotherapy some years down the road, if animal and human trials bear out its effectiveness. The article notes that smoking cannabis will not deliver significant quantities of CBD.

      • Not only can men GET breast cancer, but it tends to have a much higher mortality rate in males.

        Because most men don't know that they could get breast cancer, it tends to not be noticed until it is in an advanced state, and has likely already spread beyond the breast tissue.

      Google has failed me this morning. I remember reading in New Scientist (whose anti-drug propaganda I ranted about a couple of years ago) [mcgrew.info] that they did a study of baby boomers; the generation that started smoking ganja in their youth and are now geezers. They were trying to prove, as all these government studies from all the world's governments do, that pot is bad for you. The object of the study was to look at cancer rates in potheads vs non-potheads. They were certain that reefer causes cancer because there are carcinogens in it.

      What they found instead was that (IIRC) potsmokers who did not smoke tobacco had a 10% lower incidence of all cancers than nonsmokers. More striking, however, was the difference between cigarette smokers who also smoked hemp and buttheads who only smoked butts. The cancer incidence of those who smoked both marijuana and tobacco was half the number of those who only smoked cigarettes.

      So your study is done, the results are that cannibis prevents cancer.

      As I said, a google search for "marijuana boomer study" yielded only one hit (he he he said), to a site I'd never heard of. So I searched New Scientist and found some other interesting tidbits:
      Cannabis compound reduces skin allergies in mice [newscientist.com]
      Cannabis compound slows lung cancer in mice [newscientist.com]
      Cannabis extract shrinks brain tumours [newscientist.com]
      Cannabis can help MS sufferers [newscientist.com]
      Cannabis can protect the brain from damage from stroke [newscientist.com]

      So we have a substance that is non-addictive (habit forming but not addictive), non-lethal, fights cancer, helps MS sufferers, is the best anti-nausea agent known, stimulates appetite, yet it is illegal. So why is it illegal?

      Because it makes you lazy and forgetful, and what's worse for our corporate overlords, makes you think. You can forget about any substance that makes you think ever being legalized; thinking is the VERY last thing your government (wherever you may live) wants you to to do.

      Yes, I'm a geezer. No, I wasn't in the study. Yes, I've smoked dope. [kuro5hin.org]

I, for one, think it's really coincidental that marijuana was prohibited in the entire US in exactly the same year that the decorticator for hemp was invented - a device that sped up the processing of hemp a tenfold, thereby making it far superior to cotton for textile and far superior to woodpulp for paper.

        People will quote the special interests against it, but there's a bigger reason that dominates them all, and makes racism and the chemical company lobby fade into the background. That reason is: attitude about government.

        Americans still overwhelmingly think the purpose of government is to implement whatever good ideas come up, and solve our problems. That's why this particular article is political: people are talking about the presence of useful compounds inside the plant. People talk about how harmful it is, how harmful it isn't, etc, as though the utility of the plant, or its side-effects, actually matter.

        As long as you engage in discussion of the merits (or lack of merits) of the plant, in the context of whether or not it should be illegal, you lose. There will always be arguments against anything, whether its heroin or hydrogen hydroxide, that the material is harmful to the user. There's nothing on this earth that is provably safe.

        The debate should always be about who owns people, not the decisions that the owner makes. Is it the government's decision on what people should ingest, or the people's decision? People, stop citing the plant's advantages, and start talking about the real political issues. Don't ask "why is this illegal?" Ask, "How is does local gardening fall under the intent of the 'interstate commerce' clause?" Ask, "Why do voters in Texas have a say in Vermont citizens' health?"

    Just a thought, but I wonder if it could be possible that humans are genetically disposed to loving cannabis? It has been a commonly used plant for a long, long time. The seeds have been used as food and seem to have the perfect balance of essential fats. Now it seems we've discovered it suppresses certain forms of common cancer. Certainly, there are people who abuse themselves with it, but maybe we want them to. In my experience, the people who overuse pot are the same people who have trouble restraining many of their impulses. One of my room mates seemed to actually became a human when he was high... otherwise he was intolerable. By taking these people's pot away, we don't make them better people, just angrier.

    Another thing to note is that, while cannabis is illegal now, if we are genetically disposed to love it, cannabis will win the legal battle eventually no matter what the logic for it's legalization is. People legalize things they love and suppress the things they hate ignoring all logic in the process. You can't fight your nature. :)

    I used to think that it would be legal by the time I was thirty.

    I high school (circa 1977), at least 70% of the kids smoked regularly or occasionally.
    25% didn't care if anyone smoked it and only 5% were against it. (These numbers are all personal observation so take with a grain of salt.) The point is -- I was a geek, I occasionally did imbibe, I didn't care if anyone else smoked all day long.

    Fast forward a couple decades. Those same pot-heads are now republicans and swear that they never, ever smoked pot. In fact they believe it is immoral to do so. And anyone who does should be thrown in jail. Amazing how raising kids changes your perspective.

    I believe that alcohol is far worse than pot to your body and to society as a whole. BTW, I quit smoking pot years ago, but that doesn't mean you should.

It's a naive, domestic operating system without any breeding, but I think you'll be amused by its presumption.
