Different approaches are taken to different psychoactive substances. For alcohol, it is generally accepted that it is pleasurable to consume and the alcohol regulation framework seeks to reflect that.
For tobacco, it is not at all accepted that its use can be pleasurable or beneficial. Users can nonetheless say that they enjoy it in some way because otherwise they would not consume it. So the approach truly differs from one substance to another.
The pleasure and benefits that users enjoy from consuming a substance must be better reflected in policy development. That said, you are perfectly right in pointing out that there are different consumption patterns.
We have not mentioned today that, according to the best figures available to us, it is just a small percentage of users who consume a large part of the production. This is true for alcohol and tobacco. For cannabis, we do not have sufficient data in Quebec to clearly indicate this, but we suspect this to be the case.
In Colorado, for instance, about 20% of users account for 80% of all the cannabis consumed. Both the regulatory approach and prevention and treatment policies must therefore make these distinctions and tackle these issues head on.
