A team at Auckland's Liggins Institute is exploring the active chemical in cannabis - tetrahydrocannabinol or THC - in a bid to find a drug that produces the therapeutic effects of the raw material without the side-effects. In the interests of science, research scientist Dr Michelle Glass has a licence to possess and import THC. But despite the abundance of good quality local produce on the underground market, she has to bring the drug in from off-shore. And until it arrives, Glass is making do with synthetics - - with all experiments conducted in test-tubes. It's well known that cannabis can stimulate the appetite and suppress nausea in Aids patients and those receiving chemotherapy, says Glass. Other studies have shown that cannabis can help reduce spastic attacks in multiple sclerosis patients, as well as ease phantom limb pain, she adds. Aided by a grant from the Auckland Medical Research Foundation, Glass will spend the next two years trying to find compounds that will produce the positive effects of cannabis without the unwanted ones. When patients smoke cannabis, the THC binds to sites in the brain which trigger the activation of proteins which produce different physiological responses. The team wants to find out if they can alter the structure of the cannabis-like substances so only one family of proteins is activated - those with only positive effects. The Auckland University-trained scientist, now also a senior lecturer in pharmacology at the university's School of Medicine, is a shining example of the brain gain. Glass returned to New Zealand and the Liggins Institute last year after spending five years at the National Institute of Health in Washington DC. She turned her back on an abundance of funding and her own laboratory to return to the uncertain world of medical research in her homeland, where grants are always hard to come by. Her present research is an extension of her US studies and, especially post-September 11, she says she is sure she made the right decison. - - As well as the Auckland Medical Research Foundation grant of $50,000 a year for two years, Glass has received a prestigious Marsden Grant which will extend her studies further to morphine and other opiate-related compounds. - --- MAP posted-by: Beth
