I have a quick comment on that.
Smoking, as mentioned earlier, carries considerably more harm. We have all the lessons we've learned from tobacco to bring us up to where we are now. Some people actually mix tobacco with their cannabis when they smoke it. There are many, many years of lessons and experience to learn from and apply. Certainly the impacts on lung disease, respiratory disorders and so on are considerable.
Ingestibles—also looking at the legislation which may be around the corner regarding edible cannabis products—are a completely different process. The way it's metabolized and so on takes longer, and the effects peak within a half an hour to two hours.
