Dr. Bill,

How commonly used is the alcohol hair test? I am part of a medical professional monitoring program and just received notice that I have to take a hair test, and do not know if it is a drug hair test or if it also tests for alcohol.

Additionally, how accurate are the hair alcohol (either EtG or faee) tests? Would it determine any amount of alcohol over the last 90 days or just consistent use?

Thanks for your help.
