YES ! Lamictal can make drug test positive for PCP. Make sure you tell them or whoever you need to about being on Lamictal. Have a lab use a maspectrometer specifically for a PCP scan to officially rule a false positive.I had to do the same thing,tell them before I took the test was prescription drugs I was taking.
