I smoked weed 67 days ago, took one hit from a pinch hitter. Before that it had been over 6 months since I smoked very infrequent. I have to take a hair follicle test in the next week. I am 6'3 with dark hair. Keep my hair fairly short 1 guard on my clippers. Have cut my hair many times 5 times since. Will I pass?

Given the circumstances you describe it is highly unlikely the COOH will be detected in a hair test. Hair tests are very ineffective for detecting cannabis use even at high consumption and almost never detect infrequent use.

Despite contrary claims from the commercial hair testing field these facts have been established and repeatedly confirmed in research.

As example see:

1) Musshoff & Madea, 2006
2) Auwater, 2010

Thank you, that's a little reassuring. I have been reading other discussion boards on the Internet, and they seem to be to vague and fake. I hope if it does show, it will be below the lower threshold for a positive result. I hope you are right, this is a great job. Thanks once again!

I took 3 hit off some weed 1month ago I don't smoke just a one time thing will it show up in a hair follicle test

[DrBill100]

One time use doesn't show up on hair testing. If you are often around those that do smoke that is a greater danger in hair testing for cannabis.

I used exctasy beginning of may one time , I took a hair follicale test onn July 12 , can that test find that low level use 2 months back

[DrBill100]

How much did you use on that one occasion? Also what is natural hair color and is it coarse or fine?

[joe199178]
