most of the injury of dxm use to the body is because of the other things in the cough syrup, NOT the dxm itself...most, but not all...thats why i think the goverment is so stupid about regulating drugs. the american goverment wont sell pure dxm for cough use, because it would be used for a high, so they only manufacture if with all kinds of other, more harmful drugs...its like legalizing pot, but putting rat poison in it
