We're talking about cannabis primarily, but of course the impairment could be from other new psychoactive substances. Is it possible that the drug-screening devices we're talking about could address other kinds of impairment? I'm thinking about opioids, methamphetamines, cocaine, and the like. How are we going to grapple with that? If you believe in per se limits, do we have scientific evidence for what those numbers should be?
