TALKS LESLIE IVERSEN The Science Of Marijuana, Royal Museum, Sat 13 Apr
Prof lversen takes pot shots at the anti-pot lobby
Here we go again, yet another leftie raving on about why we should all chill man and stop stressing about cannabis. It’s not dangerous, so why make criminals out of the 7 million British people who’ve already tried it? But, when that ‘leftie’ turns out to be a pharmacology professor at the University of Oxford, you might be inclined to take more notice.
According to Professor lversen, cannabis was first wrongly classified in 19305 America when it was associated with Mexican immigration and an upsurge in violent crime. Yes, violent. Other countries followed America’s lead, and cannabis became public enemy number one, or thereabouts. 70 years on and there are distinct rumblings of decriminalisation. The British government has asked its Medical Research Council to investigate the potential of cannabis to be used for pain alleviation in multiple sclerosis and post-operative discomfort, and a private company is commercially testing the medical implications of using a cannabis extract in medicines.
Conclusive medical evidence is on the horizon, and legalisation of cannabis is not too horrific a prospect. ‘We have legal forms of morphine, and even heroin is used as a painkiller,’ states Prof Iversen. ‘They’re strictly regulated, they’re prescription drugs, and we can live with that somehow. I think we could equally well live with having legalised cannabis-based medicines without necessarily legalising the drug for recreational use.’
In the absence of concrete scientific evidence, personal reports have so far formed the burden of proof for the viability of cannabis. As a respected pharmacologist, what can lversen tell us of the objective effects of cannabis on the body? ‘Cannabis acts as a modulator of chemical circuits in the brain and the result is relaxation, eventually intoxication, and a loss of some intellectual functions like short term memory,’ says Iversen. ‘Curious things also occur, like the distortion of sense of time. Some people have visions or hallucinations, and if you take too much, it will put you to sleep.’ Hardly the dangerous, violent drug it was portrayed as in the past.
One slightly more worrying factor in the cannabis debate is the finding that cannabis use declines with age. Is it ultimately just fashionable? ‘lt’s certainly true that most people seem to give up around the age of 30,’ says Iversen. ‘and whether that’s got to do with fashion, or whether that’s got to do with taking on more responsibilities and not wanting to be criminalised, maybe the penalties become more onerous. But it would be interesting to know whether that pattern changes if the laws are relaxed.’ (Maureen Ellis) I Professor Iversen wrl/ give another talk on the value of drugs.
