my daughter did triple c's (DXM) on a wed. and thurs., and tested positive for PCP in her urine sample that was taken on a monday night. i have read it takes 3-5 days to clear, but there isn't a lot of research on the subject and everyone's body metabolizes drugs at a different rate.

it's best to stay away from that crap. i did robo when i was a teenager a few times, and i know it's fun to get high, but it is bad for you. triple c's are probably the most dangerous drug to take for a DXM high too.

stick to smokin' banana peels, or whatever you kids are into these days.
