I sympathise with the hon. Gentleman's point. That is why I have come to hear the debate. I apologise for being a little late. Is it not true that hemp drugs such as cannabis, which are widely used in the east, especially in India, are natural drugs and that the opiates which are widely used in and China and the far east are natural substances? We tolerate alcohol and tobacco, which are acceptable drugs in our society. Is there not a big difference between such substances, which have been used for centuries and about which we know a lot, and the sort of artificial chemicals that the hon. Gentleman has described, which can devastate bodies because they are not natural?
