I took a forensic labratory hair drug screen test today. I'm not sure if I will pass or not, this was for pre-employment. I have smoked marijuana a little more than 2 months ago, for about 7days and then I stopped. I have been working out and I do drink alot of water. I read somewhere that people of color often have a result that is not easily confirmed, is that true? The hair sample was taken from my chest and was not very long at all maybe 0.5inches and was a nice amount of strands. Wat do you think?
