difficult child failed his random drug screen at school on Friday. He openly told me later in the evening and swears it must be his prescrption medications causing the false positive for PCP. I was impressed he was so forthcoming about it and believed him. I googled his prescriptions and indeed, Lamictal can flag as PCP. I tried to let it go, but couldn't so I emailed the director who confirmed the test results and explained they give the kids 1 day to tell their parents about the failed test. (So he hadn't come to me on his own accord after all) His test has been sent off to the lab and we should know more later in the week. The director did say his previous random tests did *not* flag for PCP. If this was due to the Lamictal, wouldn't it flag it every time? Anyone know? If it matters, the drug test was given in the late afternoon, difficult child hadn't recently taken his prescription. Deep down, I'm afraid difficult child is using DXM again which i read would also flag for PCP.
