It will not be a part of the review, but one argument on medicinal cannabis is that if we start legalising cannabis for medicinal purposes, it will have a knock-on effect for illicit use. There is no evidence whatsoever to suggest that. In fact, in all the countries in which medicinal cannabis can be received, there has been either a stagnation or an actual reduction in the illicit use of cannabis. There is absolutely no evidence to suggest there will be an increase in illicit use on foot of legalising cannabis for medicinal purposes.
