Im currently on parole and take U.A.s for drugs and alcohol, but I work in a machine shop with lots of chemicals and sumone at work told me that if Butoxyethanol is absorbed in my skin it could show up as alcohol in my tests is this true and what other type chemicals might do this as well.

Can you get a list of chemicals from your work? I think that if you give them the list before the test then they may excuse it or tell you that you need to find another job.
I know that if you are taking prescription meds that is what you have to do.
