### Human:\nwill one time pot use show up in a hair drug test from 5 months ago? . it was in chocolate that i didn't know was there. it was about the size of a nickel.\n\n### Assistant: probably not if you are being absolutely truthful about your usage. five months is a long time for a one-time user. hair analysis for traces of thc can be quite sensitive but there is really nothing you can do at this point. if traces are detected. it is detected.
