They didn't have the ability to use oral fluids. Their per se levels were set without science and without a lot of thought.
We also have the ability in Canada to have provincial sanctions at the administrative level that support this. Our alcohol programs kick in. They can be very effective. If you look at the situation in British Columbia, where they do a three-day vehicle impoundment and three-day licence suspension for somebody in the “warn” range, it has reduced alcohol-related deaths by 50%. If we could put those types of things in place for drugs as well, simply on a failed standard field sobriety test, or a failed oral fluid test, or some combination of those, it will make us much more effective here compared with the U.S. experience.
