Well, the amendment put forward right now is about selling or importing anything, and would cover any chemical there is. If you could establish that a chemical wasn't a precursor drug, and you haven't got around to putting it on the list yet, but know that it is one of the ingredients put together into meth—which we'll stick to right now, because that's what this says here—you would be able to bring the prosecution under those circumstances.
Obviously, we or the government rely upon Health Canada to tell us which drugs should be put into the various schedules, so I can't comment on how difficult it would be to come up with an exhaustive list of chemicals. I suspect that an exhaustive list of chemicals today would not be an exhaustive list of chemicals two months from now, given the chemical ingenuity of some of the organized crime people, as I understand them.
