if they ask anything about the DXM, just tell them you had a cold a few days ago, and that might be the reason for the dxm in your system...
unless they detect a shitload.
RedRainDrop Reviewed by RedRainDrop 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
