Long-term amphetamine accelerates ageing

The use of amphetamines results in the hardening of arteries which increases more dramatically as a person gets older, a University of Western Australia (UWA) study has shown.

The research is the latest of many studies that have confirmed the toxic effects of the drug on the cardiovascular system.

The UWA researchers examined 55 amphetamine users, 107 tobacco users, 68 methadone users and 483 non-smokers over a five year period.

People with known cardiovascular disease or acute exposure to alcohol, cannabis or heroin were not included in the research.

Associate Professor Stuart Reece from UWA’s School of Psychiatry and Clinical Neurosciences said the results of the study suggested people who consistently use amphetamines age much faster than non-addicts who are occasional users.

It also found that long-term amphetamine users aged at an exponential rate.

“These findings show an increase in the risk of strokes, heart attacks, and many other arterial diseases from abuse of the substance,” he said.

When the results were adjusted to account for known causes of the hardening of arteries, the effects remained regardless.

“This shows the effects of amphetamines in addition to known risk factors for arterial stiffness,” Professor Reece said.

“The results validate results from another similar study we conducted recently on the effects of cannabis and opioids on the vascular system.”
