Please give me your opinion

Alright, so i have a hair test coming up next week...i smoked twice this past summer, both of which before mid-july. haven't touched the stuff since then, i might have had a BITE of a brownie though in early september. Do i have anything to worry about? I know this gets asked alot but this piece of mind would really help me get some sleep.

And also, i have short hair (~1"), so i figure theyll take it elsewhere...where is the next common place they usually take it, armpit?

thanks.
