Marijuana Smokers Who Start Early Are at Greatest Risk, Study Finds

Original post made by Reality, Another Palo Alto neighborhood, on Nov 22, 2010



There should be more to come on the risks of starting marijuana use early, and eventually the link to depression.

That is interesting and well designed study that joins the many studies demonstrating a clear link between schizophrenia,depression and permanent cognitive impairment caused by the use of marijuana in adolescence.
These studies are even more alarming as the concentrations of brain damaging toxins in marijuana are getting higher every year.

In a 3rd world agricultural economy such brain damages may not matter as much, In a 1st world knowledge economy they are devastating.
If people over 21 want to permanently handicap themselves I suppose they have some right to do that as long as the costs are not imposed others.

true that the other toxins in marijuana likely carry other risks as wells

Well the other toxins in marijuana are the same as in tobacco smoke with the additional hazards of residues of insecticides, fertilizers and whatever else dealers choose to dump in it.
For example, there was an outbreak of serious lead poisoning in Europe recently, the dealers added lead to the marijuana to increase its weight.

Legalize it ... until then no study is going to be worth anything. Talking about the dangers of marijuana when insecticide and heavy metals are being added to it by criminals is dishonest and stupid. Blindness used to be a byproduct of using alchohol during prohibition too ... because people would drink methyl alcohol.

Legalization with taxation is fine for those over 21yrs--- providing they do not drive or go to work with it in their system--we will have to develop a valid testing protocol first.

Ironically Holland is now closing many pot cafes and restricting the few left to Dutch citizens only.

The facts remain that those who smoked it through their adolescence will remain cognitively handicapped for life.

I would support legalization if the purpose would be to make it available to adults, while making it prohibitive, with severe penalties if made accessible to adolescents.

much worse than alcohol or cigarettes which do not unleash cognitive mayhem on certain brains.

the risks of smoking pot before adulthood are simply not public enough.

By legalizing it for over 21, it would make it an old fart drug, which is where it belongs.

"true that the other toxins in marijuana likely carry other risks as wells"

Toxins in pot, worse than the crap Big Tobacco puts in their drug delivery system? Ya gotta be kidding me.

"In a 3rd world agricultural economy such brain damages may not matter as much, In a 1st world knowledge economy they are devastating."

So Sharon, it's okay to poison the third world? You are evil.

"there was an outbreak of serious lead poisoning in Europe recently"

Two and a half years ago, abc, cbs, etc.. reported it. Google it. A one-off event. Funniest article I've read today. Doesn't pass the smell test though. That's the best ya got? Just another Paraquat scare story by prohibitionists.

Would you rather have a pothead in the family, or an alcoholic?

Rather have a stoner behind the wheel, or a drunk?

Prohibit alcohol then?

Legalize it, tax it, slice the n**s off any one providing it to kids.

First question that pops to mind..how many mentally/cognitively involved teenagers turn to pot in the first place?

In other words, which came first, the chicken or the egg, with such "conclusions" that young teen pot use leads to higher cognitive/mental impairment?

Unless this is a very poorly reported study, nothing in this article causes me to think that there is any validity to it. There is a "natural selection" bias to noting that younger teens who smoke pot end up with more cognitive/mental issues.

Correlation does not equal causality.

If you are 13, failing in school and socially secondary to mental/cognitive issues...AND have access to pot AND are in with parents who somehow don't notice that their kid is not doing well in school, is absent a lot, is somehow coming up with money they didn't give him, and smelling like pot a lot...doncha think that this kid is already in the "high risk" area of cognitive/social/psych functioning
just from the circumstances alone?

Anonyomous: Your conclusion that Sharon felt it was "ok to poison the third world" is completely wrong. Think about what she actually wrote.
I agree it sounded a little callous, but if one's highest vocational hope is pushing a plow on a small plot of land versus getting a PhD and working with computers, then what she writes makes sense in the context of her point...the effects of some brain damage may not be as devastating to the person.

okay, I should have my coffee first... that said, you are correct, it's not as much a comment about poisoning, as it is vaguely racist or supremacist.

No worries, though, in a few years they'll be saying the same thing in China and India about the US: "they're just a service economy that doesn't make anything, let them get high...."

Don't disagree with your point on self-selection.

The point is that most of the intoxicants people use came out of ancient hunter gatherer early farming communities.
The closest thing we have to that now is the 3rd world.
Many of these substances quite toxic to higher brain functions which are not a problem if only you do simple manual work and are dead by 45.
Actually the punishment for public intoxication by the upper castes in Egyptian, Roman and Aztec civilizations were very severe indeed.

These days we have the ability to design much safer intoxicants and drugs that can enhance higher brain functioning.
Also smoking as a form of drug delivery system is extremely toxic--small doses of nicotine are safe an enhance cognition---it is the smoke that cripples and kills.

"Many of these substances quite toxic to higher brain functions which are not a problem if only you do simple manual work and are dead by 45."

Okay, I'll let the China and India comparisons go. Given that the US is 38th in life expectancy, you don't mind if Europeans say "let those Americans smoke pot, they're going to die young, anyway."

Ignoring the fact this thread is about pot and you mix in terms that don't apply like "...quite toxic to higher brain functions...".

And ignoring "...most of the intoxicants people use came out of ancient hunter gatherer early farming communities."

Were there any other type of ancient communities besides hunter/gatherer or early farming?

poor research

question
"....how many mentally/cognitively involved teenagers turn to pot in the first place?"

Answer - more than you think

especially kids that want to decompress from the high stress climate in Palo Alto

that's most kids in High School,

what planet do you live in that you think only poor dumb kids smoke pot?

it's part medication

part California
