This has been a huge area of scientific inquiry with respect to looking at other substances, particularly tobacco and alcohol. How they're regulated, how they're supplied, in what potency, the outlet density you allow, and prohibitions on advertisement and promotion all can have a huge impact upon rates of use and related harms. That science could be lent to a regulated market for the taxation and regulation of the adult use of cannabis.
Certainly, things like potency or, as a prior speaker described, the relative potency in terms of cannabinol and THC are all things that can be controlled. The increasing potency of cannabis, we have to recognize, has emerged under prohibition, and there's the increased sophistication of the market in that context. We've totally handed over regulation to illegal bodies, and many of us strongly believe that if we take control of this market, we can regulate this type of thing.
