Unfortunately, this work is only one work carried out on a very small sample of 33 users and 27 non-users in the early 1980s. Although this work is important, subsequent studies have disproved much of her work. In addition, today's marijuana is not your mother's marijuana. It is a much more potent form. The University of Washington published on its website the results of several studies which have shown that THC, the psychoactive ingredient in marijuana, is known to pass from the mother to the developing fetus through the placenta. This can result in restrictions in the growth of the fetus, and in rare cases premature birth, miscarriage and stillbirth. In addition, the article goes on to say that these deficits 'appear to persist to age 10 years' and possibly on into early adulthood. Lidush Goldschmidt, et al., at the University of Pittsburgh Medical Center found subtle detrimental differences at all ages of development in their own work and that of numerous other studies, including the Ottawa Prenatal Prospective Study, which found that PME (prenatal marijuana exposure) affected the verbal and memory skills of children at 4 years of age. Furthermore, these and other studies showed detrimental effects to the intelligence of children on into the teen years. These studies are scientific and extensive, and I could not possibly summarize all of their findings for the purpose of this rebuttal to Byrne's letter. However, I urge readers to look up the works of Goldschmidt and others. Keep in mind that Dreher's study was much less scientific, and though carried on for 20 years, did not make use of the types of marijuana we have today. Finally, if I were pregnant and wanted to offset the effects of nausea, etc., I would not want to play roulette with my baby's health. Vana Meyers, Holiday - --- MAP posted-by: Richard
