Nobody is addressing present impairment, but that's my point. Right now, the current state of the law is that the defence is the medical necessity, but this is going to change the law. It's going to be perfectly legal to smoke cannabis on the weekend. Again, is it any of an employer's business what a person does on their personal time, as long as they're showing up for work not impaired?
The problem with random testing as I see it is that this person is going to test positive, and then what?
