The following is excerpted from the article you've linked to:
- Cannabis can have long-term effects on the brain, a study revealed
- Scientists say using weed before age 16 leads to underdeveloped brains
- Those who start under 16 don't have fully formed prefrontal cortex
- That's the part of the brain responsible for judgment and reason
- And, those who start after 16 have accelerated brain aging, study says
This is nothing new. It is
Reefer Madness tripe warmed over.
Please note the first sentence says cannabis
can have long term effects. It doesn't say it
will. And while it's all quite true it refers to adolescents and the same things may be said for beverage alcohol.
The human brain is not fully developed until post-adolescence, which is why we don't allow our kids to drink booze -- and why we shouldn't allow them to use marijuana in any form.
As far as "accelerated brain aging" is concerned, I was well past sixteen when I first used marijuana. I used it throughout the 1960s and '70s, while it was decriminalized in New York City. I will be 80 years old in June, 2016. I wonder how old my brain is.
Considering how many Americans are and have been regular users of marijuana there must be a lot of old brains out there. But the question occurs, what's wrong with having an older brain? Is one thereby wiser?
This tiresome "study" was conducted by the U.K.'s equivalent of our NIDA, the
National Institute on Drug Abuse, whose job it is to fabricate and exaggerate as much anti-drug propaganda as it possibly can, which it does because it is funded by Congressional committees which receive enormous amounts of "contributions" from the lavishly financed lobbies of the pharmaceutical industry, the liquor industry, the piss-testing business, the law-enforcement unions, and on and on. Marijuana legalization is a threat to them all.
