Taking cannabis `safer than aspirin'
He also found cannabis is an inherently ``safe drug'' and legalising it for medical conditions should be considered, he says.
Dr Iversen's findings will increase pressure on the British 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 than drunk ones.
The book says ``alarming claims about long-term exposure to cannabis'' should be ``put to rest''.
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. ``Despite the widespread illicit use of cannabis, there are very few if any instances of people dying from an overdose. Even such apparently innocuous medicines as aspirin and related compounds are not safe,'' he said.
