The questions posed about marijuana in your series of articles and commentaries in the issue of January 1970 are indeed challenging. Many of these questions have received more attention and more pertinent response in the literature than your contributors are aware of or, if aware, acknowledge. In fact, I am disquieted by an eclectic approach that emphasizes that lack of evidence for harmful effects of marijuana while reiterating the contrary. For example, Drs. Nader and Haggerty say "it is clear that we don't know how dangerous marijuana is," and Dr. Dews says "we know the acute toxicity is vanishingly small" (45:3).
