I was passing a roach between myself and 3 other people. I took like 4-5 puffs and I didn't really know what I was doing. But I did get high. That was on Aug. 24 its now Nov.2. I haven't smoked, nor been around marijuana or any other drugs since. I'm very anxious. Am I doomed?

What happens if you fail ?

I don't get the job

As hair can be used for 90 day detection it's a close call..

A hair drug test is meant to show consistent use over time. A 1.5 inch sample of hair, cut at the scalp line, will go back 90 days. The small amount of marijuana you used would not show up in a hair drug test, even if it was the limits of detection test which has the lowest cutoff levels. Most likely whomever is going to give you the test is going to use a basic hair drug test which has higher cutoff level which means you could do a small amount of the drug and still be negative. You should be negative.
