Thanks kaybe! This is the information I was hoping to hear, it is surprisingly hard to verify this information by googling around. I will read up on the HIPAA laws.

I actually did chat with an employment attorney...even he could not give an exact assessment of my rights without researching my questions. However, he did make the following points to me. (I am not a lawyer, this is not official legal advice!!)

1. Employer drug testing is a broad area of law, therefore it is hard to make general statements about employee rights that apply across the board.
2. Read very carefully the release that you sign! Sometimes the release is vague and releases your employer, the lab, and the medical officer from all kinds of liability! This can put you on the spot, choosing between your job and unreasonable terms.
3. It's a good idea to ask your M.D. and see if they have any input on which of your meds will cause a positive and how the privacy is supposed to be handled.

This really seems like an area where informing employees of their rights should be mandatory! I understand that employers do not want stoned employees on the job...I just think the process should be fair to both parties.
