$this->bbcode_second_pass_quote('americandream', '
')I'm a youngish (38) non-conformist communist. I have a brother and lots of friends back home in South Africa, the UK and in NZ who are nuts for smoking this stuff. My brother has the capacity of a teenager and he is 42. As a teenager, he went through long bouts of hallucinating where he heard voices in his head. I've quite a few friends who have been institutionalised after smoking this stuff. A friend tried to rape his mum while high and in a state of paranoia. My gf works with a bunch of pot smokers who are exceedingly unstable and prone to fits of unprovoked rage. In fact, her employer routinely drug tests, especially those handing heavy machinery and vehicles. Our local town council is having issues with staff, especially ones on the roads, messing up on the job. A whole stretch of the high street had to be redone because of issues with staff who turned up on the job stoned and the fact that the road went where it was not meant to.

Addicts don't want to hear these facts for the simple reason that they are......addicted. Consequently, this is a debate that only those of us who aren't engaged in this nefarious activity can engage in. The expert testimony of addicts is.....tainted and biased.


I don't know where you are getting facts about Mary Jane but its way off coarse Dude, those problems sound more like people on Crack, why not try some yourself [mary jane] it might change your old communist backwards thinking and open you up to new fresh ideas..

AD, i rarely disagree with much you have to say here on PO, but i see a serious ommission of cause and effect in your eye-witness accounts of mental illness and Maria Juana. There are such things as coincidences, and instead of MJ causing mental illness, maybe it's the other way around, that the mental illness increases the likelihood of the use of MJ or other psychotropic drugs. Now, i won't discount the possibility that the use of MJ by people with mental illness may cause a worsening of their mental illness, but its use as the principle cause of that illness cannot be proven by eye-witness accounts. By my own eye-witness accounts, there are literally hundreds of millions of adults who act like adolescents, and most of them do not smoke pot. And, to be perfectly honest about such eye-witness accounts, this description fits me, too. I'm well into my 40s, but that doesn't mean that i've matured to any significant degree. :-D Peter Pan and i have very similar genetics. The biggest difference is that he can fly, and i can't. I tried it once, and i broke my leg. And i wasn't smoking pot, either. Just stupidity on my part.

Casual Marijuana Use Causes Brain Damage

Unread postby Plantagenet » Wed 16 Apr 2014, 12:01:06

Using MRI analyses, scientists at Harvard and Northwestern have shown that even casual marijuana use among people aged 18-25 damages their brains . Two key parts of the brain were damaged---marijuana use only once a week caused the amygdala ---a key organ in the brain--- to become physically deformed. Prior studies have shown marijuana use is linked to higher incidences of mental illness, including psychosis. This study shows actual physical damage is also done to the brain, even among casual users.

Harvard study shows brain damage results from even casual marijuana use

"Smoking cannabis even casually can damage core structures of the brain, an authoritative study has found.

Just using the drug once or twice a week affects the size and shape of two key brain regions involved in emotion and motivation, the research shows.
Previous studies have focused on heavy users of cannabis – revealing that the active compound in the drug effectively ‘rewires’ the brain.
But this is the first study that has revealed the impact of casual marijuana use.
The scientists, from Harvard Medical School and Northwestern University in Chicago, analysed MRI brain scans of 20 young cannabis users aged 18 to 25.
They compared them to the brain scans 20 young people who never smoked the drug.
Professor Hans Breiter, one of the researchers from Northwestern University said: ‘This study raises a strong challenge to the idea that casual marijuana use is not associated with bad consequences.’
The scientists found major differences in two brain areas, the nucleus accumbens and amygdala. Both are linked to emotions and motivation, and also associated with addiction.
In each case changes were seen that were directly related to how much cannabis was smoked.
The nucleus accumbens of cannabis users was unusually large, while the amygdala was deformed."

Coffee, alcohol, cigarettes, lemonaide, mangos, cauliflower, the air we breathe, the water we drink, the pillows we sleep on, the shoes we wear, the websites we read, everything causes brain damage. Degeneration of the brain is a consequence of being born. Next!

Medical Science isn't right-wing or left-wing. Its just science.

Harvard Medical school is top notch---this study is the gold standard.

Here's an interesting connection. It turns out that criminals and psychopaths also have deformed amygdalas----the same kind of brain damage caused by marijuana

This isn't "degeneration" of the brain. This is damage to people's brains due to marijuana smoking. The brains of other young people who don't smoke marijuana remain undamaged. :idea:

$this->bbcode_second_pass_quote('pstarr', 'W')hile we are at it, here is something else from the esteemed establishment mouthpiece....

A new Harvard study published in the journal Schizophrenia Research has found evidence that cannabis use, regardless of how often or in what quantitieslarge_15749_madmanogbud_1333590824, does not lead to an increase in schizophrenia, despite decades of propaganda to the contrary.


Actually, the study found that :

cannabis may have an effect on the age of onset of schizophrenia

and it found:

“[b]In general, we found a tendency for depression and bipolar disorder to be increased in the relatives of cannabis users in both the patient and control samples. This might suggest that cannabis users are more prone to affective disorders than their non-using samples [/b]”

So actually the Harvard study DID find a relationship between mental illness and pot use. In families with a genetic tendency to develop schizophrenia marijuana use appears to affect the onset of schizophrenia. That means it starts earlier then it otherwise might, i.e. marijuana use triggers the onset of schizophrenia.

AND, even though Peter is apparently too bombed to understand it, the Harvard study found that marijuana users are more likely to have other mental diseases, like bipolar disorder and depression.

Harvard studies are irrelevant. Here is what will drive marijuana legisation going forward

DENVER, CO — Colorado, the first state to tax legalized recreational marijuana sales, expects to bring in an estimated $98 million in revenue this year, exceeding the state’s original expectations by 40 percent.

The Harvard studies are highly relevant. After the liberals succeed in legalizing marijuana and state governments tap into the new tax revenue stream, there is still more money to made through class action suits.

Studies like the most recent one from Harvard showing that even casual marijuana use causes brain damage just mean that some day every single marijuana smoker and every single class action attorney and every single state will be looking at suing every doctor in the US who ever wrote a prescription for "medical" marijuana. Some day every owner of a pot shop or every pot farm who is in the legal marijuana biz can expect to get sued down the road for knowingly selling a harmful product. Expect state AGs to get into the business suing to get the states reimbursed for their expenses in treating, hospitalizing and incarcerating folks who suffer mental illnesses as a result of marijuana use.

Right now we're just starting down this road---we don't even have health warning labels on legal dope yet.

Got that right, every state in the union is going to eventually jump on the bandwagon like they have with the lotto or casinos.

Oh, and alcohol has also been proven to kill brain cells.

Alcoholics do indeed suffer brain damage after years of heavy drinking.

However, the new Harvard study shows that even casual marijuana use, after several years, results in brain deformity.

Its incomprehensible to me why influential liberals want to legalize a drug that causes brain damage. George Soros, for instance, has spent 80 million on campaigns in the US to legalize marijuana. What in heck is he thinking? :roll:

Schizophrenia usually is first diagnosed around age 20, but the signs and symptoms are usually there years beforehand if one knows what to look for, so the assertion that marijuana causes schizophrenia is highly suspect.

In my work experience, it's not uncommon for people with depression to be marijuana users, but it could be argued that they use the pot to cope with the depression, which most of the time was there before the pot use started. Some people have to deal with a lot of troubling stuff, and I don't envy the position they're in trying to get help with it.

What's really interesting, to me, is the number of reports I've read about patients who are on 4 or 5 different antidepressants, antipsychotic meds, etc., have an acute episode of their illness and right away the patient's use of pot is blamed for the episode but not the cocktail of drugs the person has been prescribed by their doctor! Ever pay attention to the commercials on the tube about the side effects of various antidepressants, etc.? Freaking scary!
