Teen dagga use linked to IQ drop

2012-08-28 07:15

New York - A new study suggests that teenagers who routinely smoke marijuana may end up with a long-term drop in their IQ.

The researchers didn't find that trend in people who became frequent users after 18. That implies dagga is especially harmful to the developing brain, an idea that fits in with earlier research.

The study looked at how IQ scores changed between ages 13 and 38 in participants from New Zealand. Experts said the findings aren't definitive, but that the study's methods get around criticisms aimed at some earlier research.

Dagga smoking is relatively common in American teens. The government reported in June that 23% of high school students said they'd recently smoked marijuana, making it more popular than cigarettes.

    I agree, cannabis use amongst teenagers is not a good idea as the brain and it's wonderful quirks is still developing. However, of all the evils in this world, cannabis comes in a far last by a big distance and I feel it is relatively harmless once used in adulthood. Use dont abuse!!!

    I am not surprised, a developing mind should not have things messing with it. It is like early exposure to sex leads to sexual deviancy. This is why we need laws to regulate cannabis, not ban it. A kid has more access to cannabis than to alcohol, purely due to the unregulated nature of it. I suspect I might prefer the dagga use though, but, as with all things in life, moderation is important

      a kid has more access to weed then alchole ?? i agree with everything u say but that. all a kid needs to do it take daddies beer at the braai. look in the fridge ?? find a way into the liquar cabinet. hell they could drink cough mix or meth or something like that. i dont know anyone to ever sell to a child thats just disgusting. U need to be 21 or over

    I agree that the use of Dagga in teenagers should be a reason for concern, but posting this poor excuse of an article to try and reason with all the parents lurking on News24 is just plain dumb. First off, if you want to throw research around to seem big an important, throw the whole research document around. So that we can see if the method used is appropriate or not. There are hundreds of questions that needs to be answered first before we can legitimize such a study. I think that the News24 journalist should go out and find these things out for them selves before copying and pasting a New York Times article. Have a look at this man's perspective and tell me that this makes sense?

    Should the article headline then not have been "Adult dagga use does not effect IQ"?
