Cannabis users age faster than those who avoid the drug, a new study claims.
A study of just over 1,100 people found the drug has a significant affect on the cardiovascular system, accelerating the build-up of cholesterol in the arteries.
It means a 30-year-old cannabis smoker, for example, has the biological age of a 33-year-old, the University of West Australia researchers claim.
The study is the first of its kind to look at marijuana’s impact on biological ageing.
Its release on Monday coincided with a report presented to the American Heart Association, which looked more closely at how cannabis weakens the heart muscles.
Lead researcher Professor Stuart Reece said he was stunned by the results.
‘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 long-term effects of smoking cannabis on the cardiovascular system and there were comparatively few studies across the world looking at its long-term effects.
