That sounds about right.. but yes, DXM can definately give you a false positive for PCP or Opiate use.
Hempamasta Reviewed by Hempamasta on . PCP false positive with DXM?!?!? Just saw this experience report on erowid http://www.erowid.org/experiences/exp.php?ID=2876 Wanted to know if anyone had any additional information on whether DXM will cause a fasle positive for PCP drug testing. Wasn't sure if this was more appropriate for this section or drug testing. Thanks. Rating: 5
