The answer is that drug use is significantly detrimental to air
safety, and that drug testing policy is an effective deterrent to
drug use among safety professionals.

But there's the problem. The claim that "drug use is significantly
detrimental to air safety" does not wash, because it equivocates use
and impairment, despite your protestations.
