So basically, in summary, I think that this bill and the proposal that it's doing would put in place a complex regulatory regime in terms of who can import and who can make the products available. But what it wouldn't do, potentially, is address the underlying issues around impairment, and it wouldn't make it any safer in terms of thinking through how that works, because I think, again, coming back to just looking at the various options for testing, if you look at urine testing, cannabis can be in the system for up to four weeks—which means that you may be getting a positive test there, but you're actually not identifying impairment—methamphetamines, three to five days; other opiate-based, four to five days.
