dont worry, since dxm is legal its highly unlikely any storebought drug test will detect it, it is possible for it to show up as pcp or other opiates...more info at http://www.erowid.org/chemicals/dxm/dxm_testing.shtml
geoffrowley19 Reviewed by geoffrowley19 on . DXM and drug testing I'm wondering how long it will take dxm to leave my system like if it'll be gone in a few days like alcohol. Also would dxm show up in a hair test? I'm expected to be piss tested and hair tested by my mom regularly so i can't do weed hardly anymore because of how long it stays in you. Also if it is in my system when tested what false positive is possible to show up. Hopefully dxm is different??? Rating: 5
