'Professor Colin Blakemore, chief of the Medical Research Council, who backed our original campaign for cannabis to be decriminalised, has also changed his mind.
He said: "The link between cannabis and psychosis is quite clear now; it wasn't 10 years ago."
Many medical specialists agree that the debate has changed. Robin Murray, professor of psychiatry at London's Institute of Psychiatry, estimates that at least 25,000 of the 250,000 schizophrenics in the UK could have avoided the illness if they had not used cannabis. "The number of people taking cannabis may not be rising, but what people are taking is much more powerful, so there is a question of whether a few years on we may see more people getting ill as a consequence of that."
"Society has seriously underestimated how dangerous cannabis really is," said Professor Neil McKeganey, from Glasgow University's Centre for Drug Misuse Research. "We could well see over the next 10 years increasing numbers of young people in serious difficulties."'
