If I may, Mr. Nicholson, my recollection was that sweat was analogous to urine in the sense that—as the scientists who appeared before us said—stuff could stay in your system for 30 days. It wouldn't be used to determine impairment, but simply if you actually had consumed that drug in a certain period of time. That's what I remember.
Colleagues, any further comments or thoughts? Perhaps we can ask the department for clarification on their thoughts on this, so we all have the right information.
