I just applied for a job at Raley's, and I am probably going to get the job, but I have just learned that they do a test where they use your hair, and they can track whether you have used any sort of drug for the last six months. I'm a good kid, but I smoked some weed about 4 months ago and I am hella worried that I will fail the test. I want the job badly and I won't know what to tell my mom if I fail. Will I fail? Is there anything I can do?
