Smoking just one cannabis joint raises danger of mental illness by 40%
By FIONA MACRAE and EMILY ANDREWS

A single joint of cannabis raises the risk of schizophrenia by more than 40 per cent, a disturbing study warns.


The Government-commissioned report has also found that taking the drug regularly more than doubles the risk of serious mental illness.

Overall, cannabis could be to blame for one in seven cases of schizophrenia and other life-shattering mental illness, the Lancet reports.

The grim statistics - the latest to link teenage cannabis use with mental illness in later life - come only days after Gordon Brown ordered a review of the decision to downgrade cannabis to class C, the least serious category.

The Prime Minister is said to have a 'personal instinct' that the change should be reversed, with more arrests and stiffer penalties for users.

Cannabis has been implicated in a string of vicious killings, including the recent stabbing of fashion designer Lucy Braham.

The authors of the latest study, the most comprehensive of its kind and commissioned by the Department of Health, said: 'Policymakers need to provide the public with advice about this widely-used drug.

'We believe there is now enough evidence to inform people that using cannabis could increase their risk of developing a psychotic illness later in life.'

The analysis does not look at the age at which schizophrenia is likely to develop. However, previous studies have shown that smoking the drug as a teenager raises the risk of developing schizophrenia in one's twenties or thirties.

The researchers, from four British universities, analysed the results of 35 studies into cannabis use from around the world. This suggested that trying cannabis only once was enough to raise the risk of schizophrenia by 41 per cent.

At greatest risk, however, were heavy users, with those who took cannabis over 100 times having more than double the risk of those who never touched the drug.

With up to 40 per cent of teenagers and young adults in the UK believed to have tried cannabis, the researchers estimate that the drug could be behind 14 per cent of cases of schizophrenia and other psychotic illnesses.

'Although individual lifetime risk of chronic psychotic disorders such as schizophrenia, even in people who use cannabis regularly, is likely to be low - less than three per cent - cannabis use can be expected to have a substantial effect on psychotic disorders at a population level because exposure to this drug is so common.'

Cardiff University researcher Dr Stanley Zammit added: 'Even if cannabis does cause an increased risk of developing psychosis, most people who use cannabis will not develop such an illness.

'Nevertheless, we would still advise people to avoid or limit their use of this drug, especially if they start to develop any mental health symptoms, or if they have relatives with psychotic illnesses.'

In an accompanying editorial in the Lancet, Dutch psychiatrists said the focus on heroin, cocaine and other Class A drugs meant the dangers of cannabis had been overlooked.

'In the public debate, cannabis has been considered a more or less harmless drug compared with alcohol, central stimulants and opioids.

'However, the potential long-term hazardous effects of cannabis with regard to psychosis seem to have been overlooked, and there is a need to warn the public of these dangers, as well as to establish a treatment to help young frequent cannabis users.'

Previous studies have shown a clear link between cannabis use in the teenage years and mental illness in later life.

Research completed by leading psychiatrist Professor Robin Murray in 2005 showed that those who smoked the drug regularly at 18 were 1.6 times more likely to suffer serious psychiatric problems, including schizophrenia, by their mid-20s.

For those who were regular users at 15, the stakes were even higher, with their risk of mental illness by the age of 26 being 4.5 times greater than normal.

It is thought that, used during teenage years, the drug can cause permanent damage to the developing brain.

Professor Robin Murray, of the Institute of Psychiatry in London, warned yesterday that the risks were likely to be heightened by the increasing use of powerful skunk cannabis.

'My own experience suggest to me that the risk with skunk is higher. Therefore their estimate that 14 per cent of cases of schizophrenia in the UK are due to cannabis is now probably an understatement.'

Marjorie Wallace, chief executive of the mental health charity SANE, said: 'This analysis should act as a serious warning of the dangers of regular or heavy cannabis use, doubling the risk of developing schizophrenia - a condition in which a person may hear voices and experience strange thoughts and paranoid delusions.

'The debate about classification should not founder on statistics but take into account the potential damage to hundreds of people who without cannabis would not develop mental illness.

'While the majority can take the drug with no mind-altering effects, it is estimated that 10 per cent are at risk.

'You only need to see one person whose mind has been altered and life irreparably damaged, or talk to their family, to realise that the headlines are not scaremongering but reflect a daily, and preventable, tragedy.'

However, others questioned the link, pointing out there has been little change in rates of schizophrenia in recent years despite the rise in cannabis use and the increasing strength of the drug. __________________________________________________ ___________________

Three heavy drug users and their horrific killings: William Jaggs, a 23-year-old Oxford University student and prolific cannabis user, stabbed fashion designer Lucy Braham 66 times at her home near Harrow, the public school in North-West London.


The paranoid schizophrenic was found covered in blood beside Lucy's body, having plunged the knife into his own chest last September.

The former Harrow pupil, whose father is a teacher at the school, started using drugs when he was 14, moving on from cannabis to cocaine.

He was sent to Broadmoor secure hospital this month for an unlimited period after admitting manslaughter on the grounds of diminished responsibility.



Drug-crazed drifter Richard Cazaly is believed to have stabbed pregnant Abigail Witchalls in Surrey, in April 2005.


Cazaly, 23, who killed himself five days after the stabbing, had a history of heavy drug use dating back at least four years.

His girlfriend, Vanessa MacKenzie, told police both she and Cazaly were regular cannabis users, smoking 'a couple of joints a day'.

Surrey police said Cazaly became psychotic and violent as a result of long-term abuse of drugs and the alcohol he had consumed on the day of the random stabbing.

Miraculously, Mrs Witchalls and her unborn baby survived the attack. Her young son - who she was pushing in a pram when she was set upon by Cazaly - was unhurt.



Son of a nurse at Broadmoor Thomas Palmer butchered two of his friends during a woodland walk after his mind was warped by smoking skunk - a particularly potent form of cannabis.

Then aged 18, he virtually beheaded 16-year-old Steven Bayliss and repeatedly stabbed Nuttawut Nadauld, 14, near their homes in Wokingham, Berkshire in September 2005.

Palmer had started using the drug at 14. He told doctors he had not been smoking on the day of the killings but admitted to using skunk regularly in the weeks before the brutal attack.

In March this year, he was given a minimum 20 years in prison for the double murder.

Correction...contemplate the effects of ordering a pizza will have on the universe 10,000 years from now.

[Phlip]

I don't even smoke reefers and haven't in many many years, and I am calling bullshit on this one.

... no further comment necessary

[BustedS13]

as far as i can tell, smoking just one cannabis joint raises the danger of listening to jam bands and belief in government conspiracy to harsh your good times by over 800%

[kojisuxx]

theirs no grounds for this one. many of their cases is on people with high drug backgrounds, their not stating that they were only on weed or that they took a shit load of other drugs at the time of the murders.

[MELLO*SOS]

omg everyone who smokes herb goes nuts and butchers people! And those who don't murder people go on to develop severe schizophrenia, hear voices and suffer paranoid disillusions! LOL what a crock of shit article, great find

[S14TEVE]

hahahaha. bullshit propaganda.

Some of you need to read better I think. lol... I think the study is probably skewed as well... but I don't think it's entirely bullshit. Think about it, drugs alter your mental state, and brain chemistry. Anything that does that carries the risk of causing a mental disorder and/or injury. Even if it is small.

[Farzam]

LOOK WHAT IT'S DONE TO ME.

LOOK.

OPEN YOUR EYES.

I'M FUCKIN CRAZY MAN.

<3corn.

[kojisuxx]

i <3 murders.... i mean marijuana.

[MURPHY]

haha bullshit. im completely fine and used to smoke ass loads.

[fromxtor]

I'm going to have to go with , on this one.

[SexPanda]

Lmfao no shit it fucks up your mind. But honestly, people that do act crazy on pot are acting crazy by them selves. You ever give anyone oregano to smoke and say its weed, and watch them freak out and say they're "stoned?" Same thing.

But seriously, thats why they call pot a recreational drug. your not supposed to smoke it 3 times a day. Ive seen what that can do and its just as dangerous as alcohol. Of course some people will get addicted to it, but the majority of users do it and are able to control themselves.

And with everyone else, the use of marijuana may lead to watching Telletubbies, eating doritos and feeling "kinda like a fish".

[azndoc]

Alot of drugs are bad. But still I must reach into my wallet and pull out my....

[Farzam]

I'm so hungry right now.

[Grant]

I think the only thing ppl are going to murder is the dollar menu.

[Silverbullet]

HAH


There is no harm to the brain what so ever, even for the tokers who toke multiple times a day everyday. Thats commonly accepted information to all sorts of nuero-scientists. Close minded and simple minded people just aren't willing to accept information and drop old incorrect facts.

Theres been recent studies where they are trying to find a relation between THC and killing cancer. Theres a connection between the groupd of tobacco smokers who dont have lung cancer. Many of them smoked marijuana frequently. THC has anti cancerous properties. THC target the blood supply of cancerous cells and kills them.

http://www.sciencedaily.com/upi/inde...-marijuana.xml

Its been known to kill brain tumors in rats since the 70s but the study was shut down cuz of Govt nonsense.


Marijuana is one of the least dangerous drugs (if you even want to call it that). If you look at any credible rating of drug hazards, you'll notice marijuana is pretty far down there. Whats on top of the list are ALCOHOL, TOBACCO, amphetamines, meth, coke, crack, heroine, etc. Im sure everyone notices more and more states allowing medical marijuana. The govt realize it dosn't harm anyone, but they just dont want to admit it quite yet after spending so much $$ on this "war on drugs". They would look like idiots.

It was made illegal in the first place because of politics.

The things we do and eat in our common day to day lives affect our physical and mental health negatively WAY more than some of these so called drugs.

LMFAO!!! thats funny because its true. I worked the night shift at McD's for a month when i was 16. Only a month because that job sucked. Every other person that would walk in would be so stoned, they would forget where they were. I'd fuck with them sometimes, by saying stuff like "Hey a cop!" or "Would you like fish heads with that?" or something.

I hated that job.

Did anyone else see that report was british? No wonder thats what they think.

[fromxtor]

^^ Even if combusting it did cause cancer, all the more reason to use a vaporizer.

sooo, your chance of developing schezophrenia will go from less than 3%, to less than 4%? This is shocking!!

Three heavy drug users and their horrific killings: William Jaggs, a 23-year-old Oxford University student and prolific cannabis user, stabbed fashion designer Lucy Braham 66 times at her home near Harrow, the public school in North-West London.

Yes, the cannabis was completely to blame. the cocaine had nothing to do with it

Drug-crazed drifter Richard Cazaly is believed to have stabbed pregnant Abigail Witchalls in Surrey, in April 2005.


Cazaly, 23, who killed himself five days after the stabbing, had a history of heavy drug use dating back at least four years.

His girlfriend, Vanessa MacKenzie, told police both she and Cazaly were regular cannabis users, smoking 'a couple of joints a day'.

Surrey police said Cazaly became psychotic and violent as a result of long-term abuse of drugs and the alcohol he had consumed on the day of the random stabbing.

Again, the long term abuse of alcohol and other drugs played no role whatsoever. It was the cannabis, dammit!

Son of a nurse at Broadmoor Thomas Palmer butchered two of his friends during a woodland walk after his mind was warped by smoking skunk - a particularly potent form of cannabis.

Obviously they know exactly what caused him to snap. There were no other factors.

Unfortunately, officials investigating these cases overlooked a serious commonality between all of these attackers. The real cause for their violence was the fact that they have all regularly eaten pasta their entire lives, 2 of them starting their pasta habit as early as one year old! "People need to be made aware of the serious ramifications of eating pasta" said researcher Marissa Jones. "Eating just 3 servings of pasta a week has been shown to increase the rate of schizophrenia by over 53%."

What a bs article. as someone already mentioned, they didn't specify if everyone in the studies did any other drugs that might influence the results.

Yes, at your advanced age, it is safe to say that you will never suffer any consequences ever in your life.
