just took a hair test, you think i passed?

Soo i just got out of college and got a good job offer, but i had to take a hair test!!! fuck. I immediatly drove over to a head shop and bought the only detox shamoo they had "FresHair". I just got a hair cut the day before, a buzz with a #4 clipper; which i belive is alittle over 1/2 an inch. I havent smoked pot for 2 months i think. So i used the shamoo and went to the test the same day and they took hair off of the top of my head.

FUCK this is a good job, i kinda going crazy. Please someone tell me its going to be alright!!!!
