The second of two programmes in which Horizon and Man Alive have combined forces to examine the issues raised by "the drug problem". While scientists and doctors attempt to discover more about the chemistry of the abuse of drugs, the problem still exists - in social terms. It may be true to say that the number of deaths in this country from hard drug addiction is small, compared with, for instance, road deaths or deaths from lung cancer. But that, in turn, is only comparative. There are drug addicts in increasing number in our society today. Can we cure? Should we control? Should we care? Tonight's Man Alive looks not so much at the scientific evidence as the social consequences when both the experts and others connected with the problem debate the future with Desmond Wilcox.
