I did two small lines of coke 45 days ago and had my hair drug test was yesterday. Will that show up? Do I have anything to worry about? This was for a pre-employment drug test.. Thanks

Maybe not, but it could. You should worry about it.

All hair drug tests are meant to show consistent use over time. A 1.5 inch sample of hair, cut at the scalp line, will go back 90 days. Two lines of coc (unless they were a couple of feet long) isn't enough to show up on a hair drug test even if it was the lowest limits of detection hair drug test. I am going to say you should be negative.
