MARTIN (Letters, Sunday Times, February 7) uses the technique of concealing his main theme within a number of truisms in order to persuade us that everything he says is true. When I was a child cocaine was regularly used as an anaesthetic by dentists and I believe heroin was regarded as a powerful but useful painkiller, though it was not widely used because of its addictive potential. The use of these drugs was not absolutely prohibited by legislation. If there was a drug problem in those days, it certainly had nothing like the dimensions of our current crisis. So far from having "served its purpose'', prohibition has helped to cause the increase in illicit drug taking to the level we have today by conveying to many people the idea that because drugs are illegal there must be something attractive about their use, and by making the taking of drugs an act of rebellion for young people. Criminals have used these effects of prohibition actively to promote their wares to young people. I suspect that the whole drug problem is a monster we have created for ourselves by the simple policy of absolute prohibition and law enforcement, rather than a more rational approach.
