it may show up. it is too late to do anything about it now. the sensitivity of the lab analysis varies from lab to lab but if it shows up. you know why. even causal use of drugs for recreational reasons can come back and haunt you so i suspect you may make a different decision about using cocaine in the future. if it doesn't show up on your test then you have been given a second chance.
