Thank you, Chair.
I'll just to follow up with Ms. Wallage.
Maybe it would be helpful if you could explain to me what the connection is between impairment and THC levels. I look at some of the studies, and some of the evidence said that if you have five nanograms or more, you may not be impaired, and if you're under two nanograms, you may be impaired.
What is the connection? It seems to me that THC tells us that someone has used marijuana, but on the question of impairment, what is it telling us when someone has five nanograms versus one nanogram?
