Marijuana — Safer Than Aspirin and Other Legal Drugs 
February 22nd, 2009

Cannabis is a safer drug than aspirin and can be used long-term without serious 
side effects, says a book by a leading Oxford scientist. 

The Science of Marijuana, by Dr Leslie Iversen of Oxford University’s 
department of pharmacology, found many “myths” surrounding marijuana use, such 
as extreme addictiveness, or links with mental illness or infertility are not 
supported by science. 

He also found cannabis is an inherently “safe drug” which does not lead to 
cancer, infertility, brain damage or mental illness. Legalisation of the drug 
for medical conditions should be considered, he says. 

Dr Iversen’s findings will increase pressure on the Government to reopen the 
debate about the decriminalisation of marijuana. 

The author, a fellow of the prestigious Royal Society, found cannabis was far 
less toxic than other drugs and had “an impressive record” compared with 
heroin, cocaine or tobacco and alcohol. 

His study showed that the active element of cannabis, tetrahydrocannabinol ( 
THC ), which made users high, had a lot of potential as a safe drug to treat 
Aids patients and people suffering severe pain. 

He also found “stoned” drivers were less dangerous and able to co-ordinate than 
people who were drunk. “By any standards, THC must be considered a very safe 
drug both acutely and on long-term exposure,” he writes. “The available animal 
data are more than adequate to justify its approval as a human medicine, and 
indeed it has been approved by the FDA [American drug authority] for certain 
limited therapeutic indications.” 

The book says “alarming claims about the harmful effects of long-term exposure 
to cannabis” should be “put to rest”, and there “is no evidence the drug causes 
any impairment in fertility or sexual function in men or women”. He says people 
who stop using cannabis do not suffer long-term side-effects. 

“Cannabis does not cause structural damage to the brains of animals as some 
reports had claimed, nor is there evidence of long-term damage to the human 
brain or other than slight residual impairments in cognitive function after 
drug use is stopped.” The author says many adverse effects of cannabis are 
related to smoking the drug. 

But cannabis itself did not appear to cause cancer. Compared with alcohol and 
cigarettes, which led to more than 100,000 deaths a year, cannabis had a far 
better record. 

“Tetrahydrocannabinol is a very safe drug,” he said. “Despite the widespread 
illicit use of cannabis here are very few if any instances of people dying from 
an overdose. Even such apparently innocuous medicines as aspirin and related 
steroidal anti-inflammatory compounds are not safe. 

“Thousands of people die every year because of the tendency of these drugs to 
cause catastrophic gastric bleeding.”
