Re: Lortab and hair test
I wouldn't worry about it. If you are prescribed a medication from your Dr, an employer cannot discriminate because of a medication you take or an illness you have. Unless it interfers with that particular job in a major way. You are protected by the ADA (American Disability Act).
Most of the time employers are looking for recreational drugs like Cocaine, Marijuana, etc. Yes, opiates are checked sometimes, and Morphine will appear as an opiate. But alot of the synthetics (Hydrocodone, Oxycodone) sometimes will not show up on these tests. There is a ton of prescription meds out there. If they were test for every one, you would be pulling off more than one piece of hair.
As long as you have a script, you should be fine. Just bring it or the doctors letter to the lab.
Good luck with the new job. Take Care
