DXM can possibly show up in a blood test if they are testing you for it specifically. Any drug or chemical can be tested for if the people know what they are looking for. Now, is it most likely going to get you in trouble because they find out you used DXM? Most likely not. The reason for this is because DXM isn't on a blood test more than likely as it is not really considered to be a "serious drug of abuse". So i wouldn't worry about DXM showing up in a drug test. However, supposedly it is possible to give a false negative of PCP, but that isn't confirmed as far as i know.
