i dont know much about hair tests. ive taken a wizz quiz before and passed all times with flying colors, obviously not hard to do. but this time i was told its hair analysys and it goes back 'six months'. the last time ive smoked was in the begging of the summer, like mid june or something. since then ive been in a motorcycle accident and was prescribed loratab. but i didnt get a prescrip for the xanax i took about a week ago to amplify the effects. someone told me the weed shouldnt even register in their test but im still not sure. and as far as the xanax goes, i have no clue how that reads. but i feel kinda fucked. i was supposed to take the test monday but will end up taking it probably tomorrow. any suggestions??
