I used an edible 10mg THC chocolate on May 15th 2016. Also I smoked a pot sometime in February 2016. I have a hair follicle drug test coming in next week. That gives me only around 2 months and 6 days of no drugs. Hair test goes back till 90 days isn't it?
Also these 2 are the only times I had tried marijuana in my life. What is the chance of me getting failed in the test? I am deeply worried for the blunder I did.
Thanks in advance.

That small amount should not show. You should be OK.

A hair drug test is meant to show consistent use over time. A 1.5 inch sample, cut at the scalp line, will go back 90 days. With that small amount of use my best guess is that you should be negative.

I don't think your small usage is enough to trigger a fail or even be over the allowable limit for accidental exposure. It may not even be detectable at all, but staying away from all drugs will certainly help your chances of passing, and your confidence, and peace of mind.

THanks both of you. I have currently hair at around 1.5 inch max for the longest one. I don't have hair on chest or armpit. I have hair on the leg. As per their policy, they will take hair from leg. Does cannaboids are detectable in leg hair? I have heard that it might not be reflected in leg hair. Is it true? The lab is omega labs. WHat do you think? Just want to clear out any possibility at all. Perhaps I might cut a quarter inch more from my head. Thank you guys so much... Appreciate it..

And also as a general question? Is ingested form of marijuana has more chances of detection that the smoking one? Just for general knowing. THank u all again...

Simply best to avoid it if you are subject to testing for any reason.

What's done is done however and nothing can change that... you will either pass or fail at this point.

Thanks all. I passed the test.
