At a meeting in Southampton yesterday evening we were discussing this very idea, except that the drug was heroin, not cocain, about which I had heard before. It was suggested that the reason you get hooked on these drugs is that dopamine is what is generated, taking heroin or cocaine, which produces the pleasurable feelings. However with your dopamine cells over-producing, they are unable to produce enough for regular transmission of messages from the brain, hence the body craves more of the stimulus to get itself back into working order (it thinks!) -- Jeremy Browne, Hampshire, UK [log in to unmask] Shaking Hands BBS, Fidonet 2:252/160 (+44 1252 626233, also FAX)
