Growing up high: Neurobiological consequences of adolescent cannabis use
science daily ^ | May 26, 2019 | Canadian Association for Neuroscience

Posted on 05/27/2019 6:36:09 PM PDT by Mount Athos

About one in five Canadian adolescents uses cannabis and its recent legalization across the country warrants investigation into the consequence of this use on the developing brain.

Cannabis use was linked to impairments in working memory and inhibitory control, which is required for self-control. Cannabis use was also linked to deficits in memory recall and perceptual reasoning. Alcohol use was not linked to impairments in these cognitive functions, suggesting cannabis could have more long-term effects than alcohol.

Adolescent exposure to THC induces changes in specific a region of the brain called the prefrontal cortex (PFC) and in a brain circuit, the mesolimbic pathway, that closely resemble the abnormalities observed in schizophrenia. Furthermore, adolescent THC exposure also caused affective and cognitive abnormalities including deficits in social interactions, memory processing and anxiety regulation.

Actually according to a study I read by the Justice Department, The US Bureau of Prisons and the FBI, fully 65% of the people in prison for violent felonies, murder, manslaughter, armed robbery, sexual assault were drunk at the time they committed their crimes. I agree all drugs are harmful. However human behavior, sober or not is the most harmful . I never was, am not and never will be a prohibitionist when it comes to weed or alcohol.

Many criminals use booze and drugs.

Well isn’t that sweet that you are not a prohibitionist.

The more doped up idiots in the US the better.

George Soros agrees.

We ARE in deep trouble as a nation...

not for the reasons most of you think,
not due to drugs nor alcohol,

But primarily due to Godlessness and the
constant creeping and growing ‘social’ pograms,
drip by drip.

Here are 3 of the 10 planks of communism:
- graduated income tax,
- government controlled schools,
- government controlled healthcare.

USA has had 100 - 150 years of creeping anti-constitutional behavior. When they ‘ratified’ income tax they also took us off of the gold standard and invented the Federal Reserve, neither federal nor a reserve instead think of it as a secret bank gov’t supplied credit card where WE the people pay the interest. And no credit limit on the feds!

MJ was legal prior to 1938 & Harry Anslinger, George Washington grew it for more than just making rope, his own diary indicates he would separate the male and female plants - in order to make more potent and seedless pot.

If we citizens immediately had all our rights restored and the anti-const. laws removed, the vast majority would be absolutely paralyzed b/c they are so dependent on many many gov’t programs.

Restoring pot, alcohol, or fill-in the blank laws and use to ‘We the People’ would result in individuals mostly self-regulating. We’d have much stronger nuclear families, and much more income to allow better pursuits.

Better things would consume our time and interests rather than excess food, drugs and drinks to dull the pains and stress of not meeting our needs, desires, and responsibilities!

Make it illegal or just add restrictions and you drive demand up not down, the gov knows this.

Even I, at 57 years old and looking in a decade or so to get a little over $2K/mon for several decades, God willing, would have a hard time giving up social security.

But I’m fairly certain we’ll all have to give up some, or many, and eventually all of our gov goodies. We’ll need many more leaders and presidents as serious and knowledgeable as President Trump to truly save this country for even just a decade or two.

We Americans are too easily brain-washed rather than using the internet to uncover truths and remove the constant barrage of media, school, gov brain-washing. So sad but that’s my assessment having studied, shared and taught for 20 years at FReeper University.

Do you think it might possibly be due to the people who were willing to admit use and be studied for some extra bucks while those who don’t have a problem would very much not admit nor want to be studied in exchange for a few hundred extra dollars?

- see my other post on this thread 103.

If you study the bell curves of IQ for men vs woman you’ll find out the major reason a higher percentage of men are in prison but you’ll also find a higher percentage of men excelling in science, engineering, technology and math. Male IQ’s completely envelope the female IQ bell curve.

What I’m getting at is the most obvious stoners fit the hollywood stereotype, while those in the upper middle to high end of income and bell curve IQ do not want society to judge and therefore disqualify their professional particiaption simply for using a mild and harmless mood booster.

All of it - some are symptoms - some are causes

And it feeds on itself - the decline really started to accelerate in 2008, IMHO

Ever think that the real problem in school is the challenge is gone? I cruised thru all my schooling even my years at Purdue University studying to be a computer programmer, getting by with almost zero homework - if I couldn’t finish it in study hall or between classes in college then I usually didn’t. Sure it hurt my grades some, but even school mid-60s to mid-80s was not much or a challenge nor near as instructive as it could/would/should have been for the cost of it all.

Most everything you consume changes the brain chemistry so what? What most here need is the ability to do more deep and critical thinking.

MJ use prevalent through most countries and most of human history until Harry Anslinger and his Alcohol, Tobacco, & Firerms dept. needed something else to regulate after prohibition ended.

Sorry but universally any solution is only found in studying and rooting out the cause of troubles not the symptoms!

Marijuana does a little more than "change brain chemistry." It kills off cells and literally remodels the structure of some very critical brain regions.

FYI, substances that affect brain chemistry very often affect the physical structure of the brain.

I just went back to re-read the study - immediately jumped out at me - 19% admitted mj use - 19% of Canadians aged 15-19!

Latest saturation studies I’ve seen show mj use approx 50% using, even among 15-19 year old teenagers and younger. Any study is flawed if it doesn’t represent each component in equal proportion to what we all can see and sense if we are objective about perspectives. Too many ‘scientific’ studies are biased, often times blatantly.

I’d be willing to bet 2 things - the 19% are at the lower end of the IQ spectrum and whoever funded the study got the results they preferred.

One fairly smart FReeper taught me that if we could follow the money both public and private, and both legal and illegal we could root out all evil. The Good Book goes one better - the love of money is the root of all evil.

You implied without saying it kills off ‘brain’ cells - I’ve not seen any credible research study making that claim but I’ve seen plenty of government funded studies making wild and incredible claims. Like mj is 100 times more cancerous than tobacco.

No - which part of "the article" did you not understand? Click the link and do a search, lazy.

Not laziness. I do not typically read through entire articles based on science that has been dumbed down for lay people.

More claims from you with no supporting evidence supplied. Dog bites man.

Of course, in this case, the evidence is readily available to anyone who can do a keyword search in the PubMed database. From 1960 to 2002, there were fewer than 10,000 articles returned on a keyword of "marijuana." From 2003 until the present, over 20,000 articles have been published. I'm not going to get into an analysis of the article topics other than that they all have keyword "marijuana", but the bottom line *is* that the evidence is mounting.

I've never claimed it's benign and have stated the opposite; shame on you for such low tactics.

Um, yeah. You have vociferously denied any negative evidence about the effects of marijuana use, every time the subject comes up. Even on this thread, where I challenged your implication that a mechanism observed directly in rats does not apply to human biology, it was clear that you are still trying to promote that marijuana is benign.

Are you a spokesperson for NORML, by any chance?

What, in your view, would be “credible” research?

Given that almost all basic research is government funded, I’m really curious about your answer.

I guess that means I’m highly skeptical of modern day science or what we the general public are told. How often are these same studies contradicted or for that matter proven by another team? True science is credible when assumptions and bias are stated or eliminated as much as possible AND it is testable and repeatable, basically conforming to the scientific method.

See all of my posts on this thread beg at 103 if you want more to consider/debate.

To put it another way - how can one assume it is good science when it would not even exist without the gov funds?

Do we not see that the majority of gov studies are a gigantic black hole of taxpayer dollars?

Do they not corrupt everything and try to influence the outcomes?

No one ever died from marijuana withdrawal. Withdrawal, not medically supervised is the most lethal form of withdrawal there is. I’ve sen people almost die from it once in a rehab I was in. I’m 29 years sober off the booze and drugs.How long you been sober? As it is right now drug dealers don’t ask kids for ID, do they? And don’t ever throw me in with George Soros. Marijuana is not without side effects. But they’re nothing compared to alcohol. I was in a rehab with a guy who was literally going to trade his 12 year old daughter to somebody for a case of beer. The only thing that stopped him was as he was getting the beer a guy he knew from high school and who was in AA happened by. That
guy had what we call a spiritual awakening and went to AA.

I got nothing against you friend, I don’t even know you but I believe marijuana should be legal and an age limit of 21 for it use. Marijuana is a commodity . that means money. When you have a problem with money , you get control of the money. get control of the money and you get control of the money. Enough said. I’ll end it on that note. Peace.

Alcohol can be addictive, tobacco is the most physically addictive substance known to man even more so than heroin.

Cannabis - both strains sativa and indica - are not physically addictive. After you ingest or inhale enough to alter your mood [usually for the better] you should stop but if you don’t your body simply flushes it out. You are wasting it at that point. You can not overdose on it.

Yet a vitally needed substance for every human body, even in it’s purest form, can cause death due to overdose - water!
