Mr. Fryer, I'd like to ask you about Australia's zero tolerance for any detected amount of THC in the system in all your roadside tests. I take it that this kind of system wouldn't work in a regime such as we're facing if we legalize cannabis. We've heard testimony that people can have detectible amounts of cannabis in their system for hours or maybe even days if they're a regular user. Is it the case that this just wouldn't stand up?
