NightProwler Reviewed by NightProwler on . I would post this in the Drug Testing forum but I really need an answer by tomorrow.. I took 135 mg of DXM (9 Coricidin) 2 nights ago with my friend, and I have a drug test tomorrow for probation...will this show up? I've heard it can show up as a false positive for PCP or Opiates, but only if you took a very high dose and the test was closely thereafter...anyways, will this show up? Rating: 5
