I was given a hair follicle test on 2/10/2011. The most recent time I smoke was the evening of 1/31/2011. It was from a bowl of which I only took about 3 or 4 hits. Before this I had not smoked since Nov 27, 2010 where again I smoke from a bowl just taking 3 or 4 hits. Before this incident I had not used since August 2010. And before that it had been several years. Please tell me what the chances of my passing are? I am extremely freaked out because I am just not a pothead. I have never done any other sort of drug at any period in my life. Please help me with an answer ASAP.
