The hospital I work at(as a CNA) also did hair analysis testing when I was hired. They are not going to test for nicotine...they only test for marijuana and other ILLEGAL drugs. If someone says the insurance thing, then no hospital would hire obese nurses. Don't sweat it, but getting your hubby to quit would be pretty awesome, huh? If you are really worried about it, make sure you keep your hubby's smoke away for 3 months because that's how long it lasts in your hair.
