I'll say a few words, and then I'll turn it to my colleague, Ms. Goguen.
Back in 2011 I think what we recognized—and some of my colleagues have spoken about this—is we have tried not to take just a supply side and a total law enforcement perspective on this. What we tried to do back in 2011 was really bring in other sectors. So we brought in pharmacists and doctors to really talk about what the issues were and develop what we think are novel ideas in terms of trying to attack this issue.
The complexity around it largely deals with the fact that we are starting from something that is a legal commodity, so it's quite different from the illicit marketplace. It requires us to change our thinking in terms of what we are doing.
Let me leave it there, and I'll let Ms. Goguen address a couple of the other points you inquired about.
