Thank you so much for helping me feel at ease about this. That was a stupid thing I tried, and I really want this job I am applying for. So you think that with not using the drug for a little over 4 months, I should pass a 90 day hair drug test?
Cocaine is detected in hair test within 5-10 days of exposure (the time it takes for hair to grow enough to be included in the specimen) and is generally detectable for about 90 days.
The standard hair collection is 1.5 inches, and the average rate of hair growth (scalp) is 1/2 inch per month. By 4 months - you would be expected to have a negative hair test.
(Body hair can be used as an alternative in patients who are bald, and the rate of hair growth in other locations is slower, thus a longer detection period)
Here is some additional information on hair testing from Quest Diagnostics, one of the largest drug testing programs in the world.
thank you again for your help
