Study reveals cannabis users age faster

A study carried out by researchers from The University of Western Australia has found significant detrimental effects to the vascular system from smoking cannabis, including early ageing.

The study discovered that long-term use of cannabis increased the biological age of those studied by 11 per cent, due to the impact of the hardening of arteries in those who used the drug. For example, a 30-year-old person would have a of around 33 years old.

It is well established that cannabis use has toxic effects on the brain, lungs, respiratory system and many parts of the reproductive system, and has been linked to a variety of cancers.  However this is the first study to show that varied are not just related to malfunction of organs, but are related to an acceleration of the ageing process.

The Brisbane-based study compared 11 cannabis-only users, 504 , 114 combination tobacco and cannabis smokers and 534 non-smokers over a five-year period. Those with known cardiovascular disease or acute exposure to alcohol, amphetamine, heroin or methadone were not part of the study.

Associate Professor Stuart Reece, from UWA's School of Psychiatry and Clinical Neurosciences, said the results of the study suggested patients exposed to cannabis aged much faster than other groups in the study, including tobacco users.

"We found that for those who used cannabis over a long time, not only does it age you, it increases ageing at an exponential rate over time which is alarming," Professor Reece said.

"The level of cannabis exposure in the group studied was much higher than we have seen reported before in other studies for developed nations."

Professor Reece said it was concerning that this was the first study to look at the of on the cardiovascular system and there were comparatively few studies across the world looking at its long-term effects.

"It is important to the health of populations worldwide that such research be continued, with the study highlighting the large-scale costs to the health system from use," he said.

The study has been published in the British Medical Journal Open.

This study seems to claim some pretty strong conclusions from a very small population sample. ...not very credible to a critical read.

I cannot believe a site that is supposed to post credible science, has published this. 504 tobacco users, 114 combination tobacco and cannabis smokers, 534 non-smokers.. Over 5 years, yet only 11 cannabis only smokers?. Sounds like someone paid you to lose at least 100 cannabis only smokers data, as it did not correlate with the findings you were told to find.
Anyone with half a brain cell could tell something is not right with this "research". I didnt realise the daily mail had a science division , as this "science" is on par with their "journalism" .
Bad form.
I hope your paycheck from the pharmaceutical company helps you sleep at night

Australia is dominated by immoral drunks. No wonder why the right wing political parties have great influence there. Alcohol and pharmaceutical companies have a great source there to pay mercenaries of knowledge to misinform society about serious issues, so the rates of all sorts of mental and physical diseases grow in society to benefit their businesses, and of course, lawyers and the like.

To drdav, psychopaths do not have problems sleeping at night. They can come in the news denying global warming, then drink generous amounts of whiskey, swallow some pharmaceutical drugs, snort some cocaine, watch porn, and then sleep like babies. Those are the "leaders", they are the "intellectual elite" lol...
