Here's some short background: I've never used any drugs before. But one month ago I tried a small amount of cocoine. I have no idea if it's bigger than that safe cut off they use... But I will have a Hair drug test 110 days after I've used cocoine. That's for a job on the USA and if I don't pass I get to go back to my contry on the same day. I'm so scared of failing my test. However, I know that I have to positive 3 things on my side: It was only once and for a small amount I will have 110 days, wich is bigger than the 90 windown-detecion day most test claims to have I have perm and color hair, which I read can reduce the toxins
