Study Shows Marijuana Use In Teens Correlates To Decreasing IQ

retroworks writes "The BBC reports on a paper published in the U.S.'s Proceedings of the National Academy of Sciences showing a correlation between persistent, regular cannabis use and risk of lower IQ. The study finds the risk particularly correlates use of cannabis by teenagers who use the drug "four times a week year after year." The more people smoked, the greater the loss in IQ. Reviewers of the study at King's College Institute of Psychiatry states that the data and methodology are exceptional, but she also cautions that there may be another explanation, such as depression, which could lower IQ while stimulating marijuana use. The study does not mention or rule out 'nocebo' effects, i.e. just feeling stupid for spending your teens hanging out with potheads."

    I'd say the biggest drawback to pot smoking in teenage years is a lack of ability to find and keep a job. Being a loaf isn't conducive to paying the bills, which is the skill teenagers need to learn first and foremost. Self-sufficiency is paramount to heading off to college, or work, or simply moving on in life and I'd wager is more important than grades, social status, or if they are pot-heads or not. Its possible to smoke weed and still have a reasonable income, but the desire to be self-sufficient needs to come first or the stoner mentality wins over.

    Any behavior can become an addictive behavior. Some people become physically addicted to exercise and the endorphin rush that comes from pushing their bodies to the edge. Some become addicted to tobacco and the stimulation that nicotine gives them. Some are addicted to food. To say that marijuana addiction doesn't exist is to discount that the human body and mind can become addicted to almost any stimulation. That's not to say that all individuals who consume marijuana will be addicted but some do. So don't fully discount the potential for addiction. Some portion of the population when exposed to the ongoing stimulation will become addicted to it.

    It is impossible, and this is scientifically proven, to become physically addicted to marijuana. It's just not made of physically addictive stuff. There are no chemicals which give rise to physical dependency. Now as to the question of psychological dependency, that's a different matter however when you compare a psychological addiction to the chemical dependencies such as the endorphin rush or nicotine you are just building yourself a badly constructed argument. Also btw you will find that the actual mechanics(the movement of the hand to mouth to take a draw of a cigarette), the behavioural aspect of tobacco , is one of the habits hardest to break. Such as recent ex-smokers being out, beer in one hand and thinking it's weird not having a cigarette....

    That kind of rationalization and twisting of the use of the word "addiction" is both deceptive, and counter productive to any discussion on marijuana use. By using that definition, you must acknowledge that "addiction" is not a bad thing, and is often a really good thing. (e.g. I am addicted to living a healthy lifestyle, I am addicted to being happy, I am addicted to being a good parent.)

    When discussing marijuana "addiction", there is a clear attempt to imply an addiction to chemicals a drug which is bad, while, when being called out on the myth, declaring it to mean an addiction to chemicals that your body produces when you are happy which is not bad.

    They get defensive because results like this can be used as a reason for keeping pot illegal.

    This study can be used as evidence that it should be legal. If you have teenagers, ask them if it's easy to get pot in school, then ask them if it's easy to get a beer in school. I asked my kids that when they were in high school, and they said "of course you can buy pot in school." When I asked about beer, they laughed and said "don't be silly, of course not."

    See, it's easier for a teenager to buy pot than it is an adult. A dealer will be paranoid of an adult, because he could be the secret police, but there are no teenaged police officers.

    If you want to keep pot out of teenaged hands (and I certainly don't want kids smoking anything at all), legalize it and sell it like alcohol.
