Legal highs are a rather separate issue. I agree we must consider that they may have unintended consequences, but I would not follow that as a direct cause or link. I do not agree with that.
Dr Wollaston
May I make a little progress and then I will come back to the hon. Gentleman?
I would like to focus on cannabis for a moment—that is the issue I have most correspondence about—and on its harms. Cannabis is often presented as somehow a harmless product, and if we compare it with alcohol and consider the numbers of deaths and injuries, alcohol undoubtedly currently causes far greater harm in our society. However, before we assume that it must therefore be acceptable to legalise cannabis, I want to focus a little on its harms. In the short term, there is double the risk of a car crash for people driving under the influence of cannabis, and in the longer term, one in six young users will become dependent. It simply not true to say that cannabis is not a drug of dependence—it is.
For me, this is about the impact of cannabis on young users and teenagers, because they will double their risk of a psychotic illness. In my career I have met many families and young people whose lives have been completely devastated as a result of psychosis—I come to this debate from that viewpoint and my real concern about what psychosis does to people, because many of them did not recover. That is particularly important for those who have a family history of psychotic illness. For example, if someone has a first degree relative with a history of schizophrenia and they start using cannabis as a teenager, they will double their risk of a psychotic illness from 10% to 20%—a significant increase.
