'Reefer Mad' Mainstream Media Does It Again

What's Your Reaction:

For anyone who missed the worldwide corporate media's hysterical anti-pot headlines last week, here's a sampling:

Cannabis more damaging to adolescent brains than previously known

via Emax Health
"New research shows that teens who consume cannabis daily can suffer anxiety and depression. Smoking marijuana can have long-term irreversible effects on adolescent brains, and is more harmful to teens than previously known."


Teen marijuana use affects brain permanently: study
via CBC News
"The findings suggest daily marijuana use by teens can cause depression and anxiety, and have an irreversible effect on the brain."

Pot damage on teens worse than thought
via UPI wire services
"Daily consumption of marijuana in teens can cause depression and anxiety, and have irreversible long-term effect on the brain, Canadian researchers say."

Cannabis brain damage worse in teens than thought: study
via The Canadian Press
"The effects of daily cannabis use on teenage brains is worse than originally thought, and the long-term effects appear to be irreversible, new research from McGill University suggests."

Sounds scary, huh? It's meant to. Only there's three serious problems with the mainstream media's alarmist coverage.

1) No adolescents -- or for that matter, any human beings whatsoever -- actually participated in the study.

2) No actual cannabis was consumed in the study.

3) No permanent brain damage was reported in the study.

Don't believe me? Well then, check out the actual source of the headlines yourself.

Chronic exposure to cannabinoids during adolescence but not during adulthood impairs emotional behaviour and monoaminergic neurotransmission
via PubMed

"We tested this hypothesis by administering the CB(1) receptor agonist WIN55,212-2, once daily for 20 days to adolescent and adult rats. ... Chronic adolescent exposure but not adult exposure to low (0.2 mg/kg) and high (1.0 mg/kg) doses led to depression-like behaviour in the forced swim and sucrose preference test, while the high dose also induced anxiety-like consequences in the novelty-suppressed feeding test. ... These (findings) suggest that long-term exposure to cannabinoids during adolescence induces anxiety-like and depression-like behaviours in adulthood and that this may be instigated by serotonergic hypoactivity and noradrenergic hyperactivity."


To summarize: Investigators administered daily doses of a highly potent synthetic cannabinoid receptor agonist WIN,55,212-2 to both adolescent rats and adult rats for 20 days. Days following their exposure, researchers documented altered serotonin production in younger rats. (Why investigators presumed that the change in serotonin production would be permanent I have no idea. After the initial 20-day waiting period, researchers do not appear to have tested the rats' serotonin levels ever again.) Researchers also documented supposed depression-like and anxiety-like behavior in certain rats, based on various elaborate animal models and preference tests.


Yet somehow based on this speculative preclinical evidence, the mainstream media -- in unison -- proclaimed:

Reefer badness
via San Diego Tribune

"A study of Canadian teenagers ... found that smoking the illicit drug is harder on young brains than originally thought. Writing in the journal Neurobiology of Disease, researchers at McGill University in Montreal said daily consumption of cannabis in teens can cause significant depression and anxiety and have an irreversible long-term effect on the brain."

In truth, the purported 'study' never said anything of the sort!

So why the does the MSM consistently get the story wrong when it comes to pot? You can check out my previous thoughts on the issue here.

re: Chronic exposure to cannabinoids during adolescence but not during adulthood impairs emotional behaviour and monoaminergic neurotransmission.

This is typical of the "gutter science" used to demonize cannabis. It is a meta-analysis study, which means that the conclusions are based on guesswork, researcher bias and basic dishonesty. None of the hard sciences such as physics and chemistry accept meta-analysis as a means of proving a concept.

This study is so weak that does not offer any human examples of the effects they claim. Everything is extrapolated from a small number of rats. NO MARIJUANA was used in the study.

These claims are nothing more than fictions invented by the fevered brains of researchers (???) hoping to get grants from pharmaceutical companies to support their marketing of anti-psychotic drugs.

Why does William Randolph Hearst still control the MSM?? They just keep spouting his yellowsh_it lies.

The war on pot heads is the conservative war against hippies. Nixon JEH conspired to target liberals.

Our drug prisoners are political prisoners in the USA.

The USA has more political prisoners than any other country has total prisoners.

The MSM is just following Conservative strategy.

Based on this logic, we might want to start warning about the perils of aspirin. If you take two or three, it's an effective pain reliever. If you take 50 or so it will kill you.
08:30 AM on 12/30/2009
No, It is MUCH less than "50 or so" and my grandchildren can go into Any store and Legally buy it.

"Toxicity

Oral, mouse: LD50 = 250 mg/kg; Oral, rabbit: LD50 = 1010 mg/kg; Oral, rat: LD50 = 200 mg/kg. Effects of overdose include: tinnitus, abdominal pain, hypokalemia, hypoglycemia, pyrexia, hyperventilation, dysrhythmia, hypotension, hallucination, renal failure, confusion, seizure, coma, and death."

So, cannabis may, perhaps, with massive amounts of intake in adolescents, cause some undefined emotional problem at some point in the future. On the other hand, the pack of smokes on my desk right now will quite definately damage my health and the antidepressents I take daily have a list of side-effects that are potentially life-threatening (and no, I didn't smoke pot as a teenager).

That's a major double-standard here but one that's easy to correct. Just legalise cannabis and treat it as any other adult pleasure: Age-restricted to adults, licensed for sale and a ban on driving under the influence
01:25 AM on 12/30/2009
This is absolutely hillarious. I just saw a commercial on TV for some drug that actually said one of the side effects could be DEATH. According to the Centers for Disease control pot has never caused a death or anything close. Remember the commercial years ago that claimed " this is your brainwave on pot" except the brainwave they showed was that of someone in a coma. When they were caught their excuse was pot is so dangerous that it was OK to lie. The obvious question was , If it is so dangerous then why would you need to lie ? Legalize pot already . Its absurd for cigarettes to be legal when they cause over 200,000 deaths a year in America alone and pot is illegal ...... go figure ?

Not in itself. I have known of a few people who got into traffic accidents because they were driving while high but that's a different thing.

Link Please? Just because Cannabis Shows in a Tox-Screen does Not mean it was the Cause.
Why? because Cannabis takes roughly 6 WEEKS to metabolize out of your system b/c THC is Not water soluble, it attaches to fat cells. The Eggects of Cannabis wear off in 2-3 Hours, yet one tests Postive for WEEKS!

The Only "thing" that Is Deadly one can connect to Cannabis Are the Laws, Rules and Policies that govern it's use!

This is from the 2005 McGill University press release regarding their new miraculous "good as pot" drug discovery .

"Cannabis has been known for its antidepressant and pain-relief effects for many years, but the addictive nature and general health concerns of cannabis use make this drug far from ideal as a medical treatment. The active ingredient in cannabis — THC (tetrahydrocannabinol) — stimulates cannabinoid receptors."

But now in 2009 pot causes depression. It's a miracle.

Utterly amazing, isn't it? Well, the powers-that-be keep telling us it is not your parents' pot. . .lol. : )

Correction to my previous post: The press release was from 2005, but the point is that Dr. Gobbi has a financial interest in keeping cannabis illegal.
10:14 PM on 12/29/2009
As usual there's more to the story than the mainstream media tells us. It seams that Dr. Gobbi just this month released news that she had discovered a new drug that "raises the level of endocannabinoids — the "brain's own cannabis" — providing antidepressant effects." "The results were similar to the effect we might expect from the use of commonly prescribed antidepressants, which are effective on only around 30% of the population," explains Dr. Gobbi. "Our discovery strengthens the case for URB597 as a safer, non-addictive, non-psychotropic alternative to cannabis for the treatment of pain and depression and provides hope for the development of an alternate line of antidepressants, with a wider range of effectiveness."

Here's the link to the news release http://www.mcgill.ca/newsroom/news/item/?item_id=17777

It would seem that the good doctor's motives are anything but honest.
09:52 PM on 12/29/2009
Well, I have an idea. Lets regulate cannabis like alcohol and then the adolescent can't get it, as easy. The system, the way it works right now, hands our kids to the drug dealers at school on a silver platter. They don't card! I guess we can continue with the same system, that has not worked after forty years. That is true insanity! You want the kids to stop smoking, kill their access!

It is hard to think of what can be done. Journalists are human, and even thought they are supposed to maintain a non-biased stance, it rarely seems to happen. Maybe we will just have to be more vigilant as readers. That said, these articles, of people like this, that change the results of this study to support their position, are definitely not the type that I want tread.

You can bet the drug warriors are going to jump on this! Then, we will have another place to display their ignorance!

Fully agreed. Legalise and regulate it. Age-restricted and with a ban on driving under the influence, there's no reason for pot to be illegal.

No resaon? Are you kidding?

Big pharma needs it illegal to sell their own alternatives. The prison lobby needs to keep it illegal,. more people in jail means more profit and jobs. The lawyers need to keep it illegal, easy work for them. The textile and fashion industry needs to keep it illegal, hemp last longer than a fashion season. The timber and paper industry needs to keep it illegal or the need for wood and pulp will go down. The alcohol and tobacco industries need to keep it illegal, who wants competition? The employers associations need to keep it illegal, it lowers production profits. I can on. So can you.

Entrenched interests make money off the people by keeping it illegal. They pay off the politicians, who often also have a vested interests in keeping it illegal. Better to jail your sons and daughters than to loose such lucrative income streams.

Profit protection is the reason to keep it illegal. Screw democracy when profits are at stake.

I have been arguing that point for years! Drug dealers, like certain branches of the government, the prison industrial complex, and big Pharma have a financial interest in keeping drugs like marijuana illegal.

Sure it can cause depression-like conditions: I'm kind of depressed just from reading about the gar badge the MSM is spewing. Imagine what it must do to the poor schmucks who have to write the stuff.

LEGALIZE!
