I agree with michiganman567. (I'm also in health care.) Tobacco is a legal substance as is alcohol, but you don't see hospitals testing employees for alcohol use. What's the difference? They both can cause health problems for the individual. Why is it ok to test for tobacco? And what if the employee doesn't smoke, they use an electronic cigarette, or chew gum? Electronic cigarettes and gum don't hurt anyone else. As for a conflict of interest, does that apply to doctors who abuse medications such as adderall, oxycodone and talwin?
Random drug testing is one thing, and I don't even agree with that for the privacy issues, but tobacco testing is taking things too far. It's becoming about conformity, not about what affects the health care of the patient.
