hair follicle test 1hr notice

I went to hopefully new place of employment expecting a p test and they told me it would be a hair test irushed and got an all clear system and used it all over and they shaved hair off my arms what are my chances of passing? smoked for about 3 weeks untill last week am im fugged?:(

sorry ur probably fucked, except sometimes they don't test every sample, just use the threat of testing to keep you scared square.
