Jack Layton, leader of the federal NDP, may have broken a political taboo, but his comments won't surprise the millions of Canadians who, from time to time, use marijuana "responsibly." Marijuana, used in moderation, can induce a gently altered mental state that not only enhances enjoyment of food, music, lovemaking, etc., but might sometimes genuinely enhance certain kinds of thinking. In a carefully controlled experimental study that my colleagues and I reported some years ago, there was clear evidence that, for some people, smoking marijuana can improve certain "right hemisphere" pattern recognition-integration abilities, even while modestly reducing certain "left hemisphere" verbal-analytical abilities. Whether this trade-off is worthwhile would presumably depend on what one wants to accomplish while "high." Richard A.
