We are concerned by the marijuana misinformation in circulation – and in particular by the number of “expert” sources ignoring relevant scientific data. These include organizations such as the Vermont Medical Society, the Vermont Academy of Family Physicians, the Vermont Psychiatric Association, the Vermont Association of Child and Adolescent Psychiatry, the Vermont Chapter of the American Academy of Pediatrics, the Vermont Chapter of the American College of Physicians, the Vermont Public Health Association, Vermont Department of Liquor Control, the Vermont Department of Health, and individuals such as Dr. Paul Parker of Richmond. Why are so many experts repeating half-truths and outright falsehoods? This is especially disturbing because we Vermonters look to these medical and scientific bodies to inform our marijuana policy discussion. Further, when young people learn the real science, or gain experience of their own, they develop a legitimate cynicism that undermines their trust in our institutions. Hence, we write to promote greater integrity on the information-based side of our marijuana policy discussion.
