That, of course, is not any of my five suggestions. What I'm suggesting is that if they're in a safety sensitive position, and the random cannabis and other drug testing takes place, once there's a positive test, there be an inquiry into whether or not there's a medical authorization or a medical condition for which you need to have one. In the meantime, you're taken out of the safety sensitive position so that you don't hurt yourself or others, and it's dealt with appropriately.
If they are under the influence such that they are impaired, even though they were ingesting a legal substance.... Do you want to get on the plane if the pilot is impaired?
