How could cannabis alter the teenage brain?
BBC news health ^ | august 28, 2012 | james gallagher

"When a teenager smokes cannabis are they permanently damaging their brain and dulling their intellect for a lifetime?

The dangers of smoking cannabis, and the potential health benefits, have been a source of controversy for many years.

The latest study on the drug suggested heavy and prolonged cannabis smoking as a teenager resulted in a permanently lower IQ. You can read Dominic Hughes's report on the findings here.

But how could cannabis have this effect on the brain and why might teenagers be particularly susceptible?"

Another "MJ Permanently hurts your brain" piece ~ sounds pretty reasonable, but the permanent damage part made me sit up and pay attention

That 'splains so much from Obama's incredible ignance to the question of where do Democrats come from.

There are other articles on the same BBC page involving other studies, etc. Worth reading.

Now ~ whoops ~ wait a minute (GOES to WINDOW) (SHOUTS) "Hey you kids, get off my lawn" (WINDOW SLAMS SHUT) ~ You get the idea why that's really necessary these days.

How could cannabis alter the teenage brain?

Make it more interested than it would otherwise be in sex, drugs, rock & roll, and junkfood?

Is that possible?

Obama was a Choom guy,
Puff, puff, puff.
Fried his brain,
Sure enough.

Then came the Con,
From Chi to DC,
Where incompetence can hide
AND be very PC.

Nobel Prize, and Corporate Jet,
Goes to the Choom guy,
Puff, puff, puff.

What is missing in this discussion is - what IS cannabis?

Is it a plant that people have dried the leaves of and smoked for over a 1,000 years? Or is it the doctored concoction that people have manipulated to increase the potency more than 10 times?

I have heard many people from my generation say things like, “well everybody did that when we were in college, and everybody turned out OK.” They don't seem to understand that was was called “pot” in the ‘60s, and what is called “pot” today - are two completely different animals!

Thanks for the clarity. I was going to say I turned out to be a very successful engineer so I wasn’t effected by it back in the 70s. Today’s pot isn’t the same. I wonder if the low power stuff is even available today.

I've read about some that's carefully bred and grown hydroponically in very controlled conditions that is as you describe. I have doubts that's really an accurate assesment of what's commonly sold on the street.

How could cannabis alter the teenage brain?

LOL! The article talks about an 8% variation between the teenage years and the age of 38.

Yet someone one the net who make a profession of administering IQ test says:

The norm group with which your test score is compared, has an average score of 100 and a standard deviation of 15. A standard deviation is a measure of the spread, in this case of the IQ score. If the standard deviation is 15, 68 percent of the norm group scores between 85 (100 minus 15) and 115 (100 plus 15).

As I undeerstand it, that means 'standard' IQ tests have a 30 point spread. If their IQ drops 8%, that would translate to 12.5 points [assuming they started with an IQ of 100].

The site also says:

In comparison to the entire population, your IQ score will increase until you reach 'adulthood' and will decrease as you get older. This is simply a consequence of the maturation of the brain and an increasing understanding and vocabulary.

As people get older, it becomes more difficult to focus and the quality of their memory decreases. This leads to a decrease in performance, although the absolute decrease is often minor.

From here: http://www.123test.com/iq-scores-and-differences/

-----

Sorry, but with the standard deviation and aging factor, I see this as other correlation-means-causation study, nothing more.

Or in the case of some of my former classmates, it makes them hold down jobs as busboys and cab drivers at age 50 because they spent all of their formative years getting high instead of studying.

I can pick out certain pot users because they have a specific subtle lisp in their speech. I can’t quite pinpoint what it is exactly, but I know it when I hear it.

Abnormal psych texts at the library will tell you that long term pot smoking causes the same damage as doing LSD and can cause you to become psychotic.

What is so unexpected about long term damage with anything that effects your brain? Seriously? No blood goes into the brain, but lots of other stuff gets in. It’s really rather remarkable.

Well, I didn’t until my late teens thru 20’s. And while at the time I saw no real problem, looking back later I realized how much ambition it killed. I wanted to make enough money to keep my car on the road, pay the rent and buy more pot. I didn’t care about raises, getting into a better job, learning more. It just killed ambition to be more than I was. And in my present job I still feel like I’m 5 years behind in my knowledge than I should be.

Booze being harmful doesn't make mJ less harmful than it already is.

You are comparing apples and oranges, i.e. group performance/standard deviation and individual performance.

Individual performance does not have a standard deviation of 15. Losing 8% in the transition from teenager to prime adulthood indicates pathology.

It is normal for an individual to perform better on IQ tests in prime adulthood than they did as teens.

I teach AP Psych, the instructor at a workshop said that he had read an article that claimed that increased drug use while the brain is still developing contribute to the increase in later adult schizophrenia cases. On 1 level is does make sense but he didn't have the article and I have not been able to find it.

When I look at the parts of the world that have used Cannabis and Hashish for thousands of years, and compare them to the parts of the world that have used alcohol for thousands of years, I don’t see that.

Since teens report that they can get pot more easily than beer or cigarettes, it looks like the most effective way to keep pot out of teens' hands (and still-developing brains) is to legalize it for adults - so sellers have an incentive not to sell to kids (namely, the loss of their legal adult sales).

Then we can start sending adults to prison for contributing to the delinquency of minors by buying them mj.

"Thousands of years" means nothing. Actual per-capita marijuana consumption and percentage usage rates matter more. Take that into account, and your implied conclusion gets inverted:

Then we can start sending adults to prison for contributing to the delinquency of minors by buying them mj.

We already send adults to prison for buying mj - whether for themselves, another adult, or a minor. Tacking on another charge would increase the disincentive marginally, while requiring proof beyond reasonable doubt not only of the purchase but of the subsequent transfer to a minor.

Wasn't the pot selling side concerned with that issue?

That's exactly the point: the pot selling side is not currently concerned with the illegality of selling to minors because the pot selling side already breaks the law by selling to anyone. This is why teens report that they can get pot more easily than beer or cigarettes. If the pot selling side could legally sell to adults, the pot selling side would have an incentive not to sell to kids (namely, the loss of their legal adult sales).

No, the dominance of it, and the accumulated effect on creating the people’s culture and societies is what matters.

The very short period of Cannabis use in the west already seems to be having the predicted effect, over the last 60 years.

The west will have to get used to more socialism, and government dependency, as more and more voters are seduced and ensnared by the pot culture.

What is in it now?

From my retired cop friend, apparently ANYTHING that the grower/seller thinks will make the buyer think it is stronger, and therefore worth more. His comment was, “it could be dosed with anything if they think it will bring more.” There is also apparently a belief that soaking the seeds in various chemicals will increase the effect and therefore the price. The long term effects of all this nonsense is tested by - nobody.

"According to my opinion, and the opinions of many defectors of my caliber, only about 15% of time, money, and manpower is spent on espionage as such. The other 85% is a slow process which we call either ideological subversion, active measures, or psychological warfare. What it basically means is: to change the perception of reality of every American that despite of the abundance of information no one is able to come to sensible conclusions in the interest of defending themselves, their families, their community, and their country.
 
It's a great brainwashing process which goes very slow and is divided into four basic stages.
 
The first stage being "demoralization". It takes from 15 to 20 years to demoralize a nation. Why that many years? Because this is the minimum number of years required to educate one generation of students in the country of your enemy exposed to the ideology of [their] enemy. In other words, Marxism-Leninism ideology is being pumped into the soft heads of at least 3 generation of American students without being challenged or counterbalanced by the basic values of Americanism; American patriotism.

Maybe when we understand and take responsibility for what our American Founders articulated when they implemented the Declaration of Independence; intent upon manifesting a Republic where "NOTHING IS MORE CERTAINLY WRITTEN IN THE BOOK OF FATE THAN THAT THESE PEOPLE ARE TO BE FREE...
