Smoking cannabis virtually doubles the risk of developing mental illnesses

It kind of makes you wonder why George Soros is leading the way to legalize marijuana.
I guess he thinks that it's easier to rally pot heads to his cause.

Not to mention that the amount of tar inhaled by marijuana smokers and the level of carbon monoxide absorbed are three to five times greater than among tobacco smokers.

This is why people started using vaporizers and even a waterpipes help with this also for smoking.
Please, pull your ignorance up, your ass is showing.

Please don't leave out that the smoke causes curtains to yellow. Damn these godless hellions and their immoral shenanigans.
Not to mention that the average cigarette smoker smokes much more tobacco every day than the average marijuana smoker.
Another study:
Doctors link marijuana to mental illness
The American Psychology Association APA online, Psychology In The News
United Press International - January 16, 2005 LONDON, Jan 16, 2005 (United Press International via COMTEX) -- British doctors have connected marijuana use with rising rates of depression, psychosis and schizophrenia.
The Royal College of General Practitioners said that acceptance of the drug and greater availability of stronger forms of it were leading to rising rates of depression, psychosis and schizophrenia, The Telegraph of London reported Sunday.
"Health warnings are falling on deaf ears, drowned out by the cries of powerful liberal pro-legalization groups," said Dr. Clare Gerada of the college's drugs misuse unit.
"There is clear evidence that high levels of use, especially among teenagers who are physically and mentally still developing, carries with it the increased risk of psychosis and respiratory conditions such as asthma," she said.
More worrying, Gerada said, was the increase in super-strong versions of the drug, known as skunk. "The truth is, genetically modified forms of the drug are the norm," she said.
The British Medical Journal in its January 2005 issue revealed that smoking cannabis once or twice a week almost doubled the risk of developing psychotic symptoms later in life.
Robin Murray, a professor of psychiatry at King's College London, has said that since the 1980s doctors have begun to see a link between psychotic symptoms and cannabis.

And another:
Cannabis link to mental illness strengthened
NewScientist.com 21 November 2002
The link between regular cannabis use and later depression and schizophrenia has been significantly strengthened by three new studies.
The studies provide "little support" for an alternative explanation - that people with mental illnesses self-medicate with marijuana - according to Joseph Rey and Christopher Tennant of the University of Sydney, who have written an editorial on the papers in the British Medical Journal.
One of the key conclusions of the research is that people who start smoking cannabis as adolescents are at the greatest risk of later developing mental health problems. Another team calculates that eliminating cannabis use in the UK population could reduce cases of schizophrenia by 13 per cent.
Until now, say Rey and Tennant, there was "a dearth of reliable evidence" to support the idea that cannabis use could cause schizophrenia or depression. That lack of good evidence "has handicapped the development of rational public health policies," according to one of the research groups, led by George Patton at the Murdoch Children's Research Institute in Melbourne, Australia.
The works also highlights potential risks associated with using cannabis as a medicine to ease the symptoms of muscular sclerosis, for example.
Pharmacological effect
Patton's team followed over 1600 Australian school pupils aged 14 to 15 for seven years. Daily cannabis use was associated with a five-fold increased risk of depression at the age of 20. Weekly use was linked to a two-fold increase. The regular users were no more likely to have suffered from depression or anxiety at the start of the study.
The reason for the link is unclear. Social consequences of frequent cannabis use include educational failure and unemployment, which could increase the risk of depression. "However, because the risk seems confined largely to daily users, the question about a direct pharmacological effect remains," says Patton.
In separate research, a team led by Stanley Zammit at the University of Cardiff, UK, evaluated data on over 50,000 men who had been Swedish military conscripts in 1969 and1970. This group represents 97 per cent of men aged 18 to 20 in the population at that time.
The new analysis revealed a dose-dependant relationship between the frequency of cannabis use and schizophrenia. This held true in men with no psychotic symptoms before they started using cannabis, suggesting they were not self-medicating.
Genetic factors
Finally, researchers led by Terrie Moffitt at King's College London, UK, analyzed comprehensive data on over 1000 people born in Dunedin, New Zealand in 1972 and 1973.
They found that people who used cannabis by age 15 were four times as likely to have a diagnosis of schizophreniform disorder (a milder version of schizophrenia) at age 26 than non-users.
But when the number of psychotic symptoms at age 11 was controlled for, this increased risk dropped to become non-significant. This suggests that people already at greater risk of later developing mental health problems are also more likely to smoke cannabis.
The total number of high quality studies on cannabis use and mental health disorders remains small, stress Rey and Tennant. And it is still not clear whether cannabis can cause these conditions in people not predisposed by genetic factors, for example, to develop them.
"The overall weight of evidence is that occasional use of cannabis has few harmful effects overall," Zammit's team writes. "Nevertheless, our results indicate a potentially serious risk to the mental health of people who use cannabis. Such risks need to be considered in the current move to liberalize and possibly legalize the use of cannabis in the UK and other countries."

Findings that use the words "not likely" and "may" don't seem very intriguing. If there are changes in the brain from long-term use, nobody has actually been able to track those down thus far.
You'd think after all the years of studies that researchers would actually be able to nail something concrete down for the anti-pot argument. But this study appears to be another failure.

BULLSH8! I've beeen around pot smokers since I was a long haired musician in the 60's, and I still enjoy a toke, now and then. I've known guys who rolled out of bed, lit up and kept stoned all day, and they had their own problems, but that was because they had problems, pot or not.
Most people don't smoke 20 1/4" thick joints a day (the equivalent of a pack a day tobacco smoker) by themselves. In fact, if they could, and they were still standing after the first joint that big, they got burned because the crap they bought wasn't worth squat. If the pot's that bad, lighting up is wasting a perfectly good match.

YEA!! Another old fogie who takes a toke off a bud pipe every now and then. I thought everybody was afraid to smoke any pot because they might have to pee in a bottle. Isn't that a requirement of the Patriot Act.
Hey Rip, smoking pot makes people paranoid because they're afraid someone like you will turn them in. :laugh:
This is the only comment made so far that I am sure is correct. Which always made me wonder why those that would ban cigarette's in public areas would push for legalizing marijuana.
For medical reasons it SHOULD be legal. So what if it causes lung cancer 20 years, or even 10, later. If you are most likely going to die in the next 3 years.

Bullshit RIP.
Weekly Church attendance and "Speaking the Truth" to a bunch of anonymous message board people Doubles your Mental Health Risk. One only has to look at your posts to see that.

Obviously you are one that says cigars don't cause cancer. After all, look at George Burns claims to have smoked at least one cigar every day for most of his life.
Now, given your signature, I will proclaim you to be a liar whose very words support the tobacco industries which have directly led to millions of people dieing. thus, Harvey lied and millions died. After all, you can't prove your claim. Right?
Fix your signature, it is wrong, you know it, and thus, it really is a lie.

I see, Harvey has to prove something for it to be true, but you only have to proclaim it for it to be true.
Why doesn't that surprise me????
