No fireworks, host and guests being in basic agreement, but a productive discussion of how psychoactive drugs work, and how social pressures work. LG: "It seems clear to me now that marijuana is a harmful drug, in the sense that any psychoactive drug is a harmful drug, but if one puts it-" WFB: "How do you define psychoactive? Is alcohol psychoactive?" LG: "Yes." WFB: "How about cigarettes?" LG: "Yes." WFB: "Okay, is Coca-Cola?" LG: "Oh, Coca-Cola has enough caffeine that it might be considered a psychoactive drug." WFB: "How about lemon squash?" LG: "I don't believe so; but I would have to-" WFB: "Well, then everything is psychoactive-everything good." LG: "Well, no, but lots of things are, more things than most people suspect. But the point is, it's not that I am saying marijuana is a harmless drug, but that in fact its harmfulness ... is far less than the harm which we are imposing on young people through the present approach to its social use." ... LM: "I was really concerned about why some kinds of people really did seem to get dependent on drugs.... And it seemed to me that scapegoating the drug by saying that this marijuana would come into your life and make your son into a hippie was begging the question."
