Pubdate: Sat, 11 Jan 1997 Source: Austin-American Statesman (TX) Author: R. J. Givens Max Stanley Chartrand (Letters, Jan. 3) claims that there is not a single known medical necessity for prescribing or using marijuana. THC and other cannabinoids have been extracted for pharmacological uses and are readily available by prescription without ever needing to resort directly to marijuana use''. Chartrand already contradicts himself by admitting that THC is a valid medicine after denying that the source -- marijuana -- is also a medicine. It's like saying that vitamin C in a pill is good, but vitamin C in an orange is worthless. AIDS, cancer and chemotherapy all produce devastating nausea, vomiting and wasting from slow starvation. When nausea relief is needed most, Marinol is worthless because it is impossible to swallow the pills Chartrand promotes so carelessly. Marijuana is vastly superior to THC pills because when you are in the pits of hell heaving your guts out, a puff or two of good cannabis instantly stops the nausea and vomiting. I know from first-hand experience. Marijuana also stimulates the appetite, enabling AIDS, cancer and chemo patients to regain the weight they lost to slow starvation. Oncologists know that marijuana works because they see the fatal weight-loss spiral arrested and reversed by pot-smoking patients. Many patients regain their normal weight. Enabling these people to eat is literally a lifesaving necessity. This most certainly makes marijuana a valuable medicine. It's time to end the intellectual bankruptcy and moral delinquency known as drug prohibition. R.J. GIVENS San Francisco, Calif. Via e-mail
