Dr.Bill,
I have read almost all of your posts on this subject and I am like everyone else that would be reading such things in that I have consumed marijuana recently and will be subject to a HDT in a couple of days. I have two questions that I would like your opinion on. 1) How can I be sure the lab testing my hair will only be testing for THC-COOH. If I understand correctly, this is the only metabolite that can't come external exposure? 2) I have smoked 4 times in the last 90 days averaging about 6 hits each time. I spoke to someone at the testing site and they said they take 1" hair samples (so I assume that will go back 60 days) The heaviest smoke session was almost 90 days ago. What are my chances of a negative result?
Incidentally, I had someone I know call the actual lab doing the testing and an executive at the lab said that hair testing will not catch someone who just smokes every other weekend.
