Cannabis use in teenagers and the long-term risk to IQ

This week a report has been released illustrating a new facet of potential harm from cannabis. In a long-term study (carried out by scientists in Otago, at Duke University, USA and King’s College London), IQ and cannabis use were monitored over 25 years from age 13 to 38.
Of particular interest, their study of over 1000 subjects included teenagers in whom IQ was checked before any cannabis exposure. Around 1 in 7 reported being regular cannabis users, 1 in 20 doing so at least weekly before the age of 18.
What did the investigators find? With no cannabis history, there was a small decline in IQ. However recurrent cannabis use was associated with an 8 point decline in IQ, comparable to that seen in early dementia. Importantly, this decline in IQ was particularly marked when cannabis use began during teenage years. A further concern was that stopping cannabis use did not lead to recovery of the IQ loss. Commentary on the results has ranged from concluding that cannabis is harmful in teenagers but safe in adults, to more cautious notes that adolescent brains appeared more vulnerable to cannabis, without providing carte blanche for longer term safety of cannabis use in adults.
I been knowing this because weed heads are ? dumb.

A study, published in the Canadian Medical Association Journal, examined whether marijuana lowered intelligence levels in users. The study was largely ignored by US media, while within Canada, the results seemed to depend on which newspaper headline you read.
Most headlines about the study said something like "Potheads become dopes" (Toronto Sun) or "? does rot your brain" (Edmonton Sun). Yet a few papers reported the opposite, announcing that "Marijuana Doesn't Make You A Dope" (Calgary Herald) or "Smoking ? No Risk To IQ" (Globe & Mail).
That a single study could produce such conflicting headlines says more about the integrity of the media than it does about the study itself.
Here's how the study was done: A group of young, middle-class adults was assembled, consisting of non-tokers, light ? smokers, and heavy users. Light users were those who smoked less than five joints a week, heavy users toked an average of 33 joints each week. Researchers used ? samples to confirm marijuana use or abstinence.
What this study would seem to show is that moderate use of cannabis produces an increase in IQ, while heavy use produces a decrease. Further, the study shows that even heavy, long term use of cannabis produces no permanent harm to IQ scores. -
Since when did we care so much anout what happens to sumone's IQ...and if thats the case , what does alcohol do to the IQ??

Hello Brave New World.
"..there is always soma, delicious soma, half a gramme for a half-holiday, a gramme for a week-end, two grammes for a trip to the gorgeous East, three for a dark eternity on the moon..."
"you do look glum! What you need is a gramme of soma."
"A gramme is better than a damn," -
On the real tho, ? doesn't ? with your IQ
It just ups your IDGAF meter when high
But if you think some of the brightest minds weren't on some kinda of drug
You are gravely mistaken... -

Musicians and rappers don't count as being classified as having the brightest minds. -
