My friend’s young son who didn’t know better went out the night before he had to take a blood test for a new job. Not a smoker, but has a few “socially” when out. It showed up on his bloodtest and was included in his health report for the job, which classified him as a “smoker”. My guess is that is how they will police it—if anything shows up in a routine medical test.
This is a tough one to enforce, but if they want to give you a bllod test every time you see a doctor, it can be detected.
- or - they’ll have mandatory random urine testing - some nicotine nazis will come to your place of employment, and if you test positive, it will be over for you.
they check carbon dioxide in the blood i believe.
