Sterle, Jr. 'HARMLESS' POT CLOUDS ISSUE Editor: Re: Lighting up is bad either way, May 20 letters. I strongly agree with letter-writer M. Downey on this issue. I, a former pot-consumer - along with most of my former pot-consumption peers who I've bumped into these last half-dozen years - - can attest to the permanent damage that marijuana can cause to the consumer's body and mind. Scientific proof of such potential damage? For one, there are the startling facts published in The Guardian newspaper in 2002; it was authored by Robin Murray, professor of psychiatry at the Institute of Psychiatry in London: "In the mid-'90s, a Dutch psychiatrist named Don Lintzen, from the University Clinic in Amsterdam, noted that people with schizophrenia who consumed a lot of cannabis had a much worse outcome than those who didn't. This was confirmed by other studies, including a four-year follow-up at the Maudsley Hospital. Those who continued to smoke cannabis were three times more likely to develop a chronic illness than those who did not consume the drug," Murray learned. "Why does cannabis exacerbate psychosis? In schizophrenia, the hallucinations result from an excess of a brain chemical called dopamine. All of the drugs that cause psychosis - amphetamines, cocaine and cannabis - increase the release of dopamine in the brain. In this way, they are distinct from illicit drugs such as heroin or morphine, which do not make psychosis worse." If pro-pot people propose legalizing marijuana for practical reasons - e.g., less pressure on already-overburdened law-enforcement and justice systems - that's a clear and perhaps practical motive. But there's simply way too much of the media-propagated BS out there implying or outright declaring to our impressionable youth that pot is harmless. Frank G.
