STRIKES GOLD WITH POTENT CROPS BRITISH Columbia marijuana is prized through-out the world because of its potency. Run-of-the-mill marijuana contains only 2 to 3 per cent tetrahydrocannabinol, or THC, the active mood-altering ingredient. B.C. pot is stronger. Some hauls seized by the RCMP have contained as much as 15 per cent THC. Two years ago, marijuana from Surrey, B.C., won an intemational pot award, according to RCMP Constable Vince Arsenault. But is high-potency dope more dangerous to the health? To find out, The Star contacted Robin Room, a scientist affiliated with the Addiction Research Foundation division of Toronto's Addiction and Mental Health Service Corp. Room co-authored a recent study done for the World Health Organization on the relative risks of marijuana use. This study concluded that marijuana - while harmful to the health - is less so under current use panems than either tobacco or alcohol. The study received some notoriety when WHO refused to publish it. Critics charged that WHO was worried the findings might be seen to contradict Washington's war on drugs. The study will be published instead by the Addiction Research Foundarion in a book due out this fall. On the question of marijuana potency, Room said the answer depends on how people smoke. Most users, he said, smoke only enough to reach the desired level of high. In that case, he said, the higher the THC content in the marijuana, the less users smoke. Since much of the damage from marijuana comes from inhaling the tars in the weed, high-potency pot should actually be safer than traditional low-THC brands, he says. "Naive or first-time smokers might smoke too much," he said. "But I would expect experienced users to smoke less." -- Dave Haans Graduate Student, University of Toronto WWW: http://www.chass.utoronto.ca:8080/~haans/ - --- Checked-by: Mike Gogulski
