It would be more along the lines of a fraction, a small fraction of 1 hit. I was recently clean for 110 days, smoked 1/4 gr of Mexican and within 2 hours my urine was over the 50ng/ml for a home test. I realize that is urine and your talking hair, but if that much was in my urine, then my hair must certianly have been filtering the THC also.
I was of the opinion that hair test in general, used the 50ng/ml cutoff level. But I could certianly be mistaken. I did a Google, but could not find hair test cutoff levels. It is true that GC/MS can detect down to 1ng/ml, but if that is the cutoff level, it would be a sad day. Please post any more info you find on the test and I'll try to make some phone calls tomorrow and post what I fine. N2
IamN2pot Reviewed by IamN2pot on . Hair analysis test I used to be a hard smoker, smoking at least 4 times a day 3-4 hits each session. Recently, February, I reduced my smoking to occassional use. I used the last week in March (at the most 5-10 hits total) and then one hit in April and finally one hit at the beginning of May. I just recently started looking for a new job and they have pre-employment drug testing-hair analysis! I guess I really impressed them in the interview because I got a call back only 4 days later. Today, I had to take Rating: 5
