I do know that there's a certain amount of rigour around anything we do with respect to our drug formulary and what's accepted or not. We look at research, and I know that there's a department that specifically drills into it.
On medical marijuana, I've seen some discussion around that and where the world is going, so to speak, but we're sticking to the clinical evidence so far and the top research says about whether it really makes a difference or not. That's where we are right now.
