Well, why dont you figure out, or at least research the effects of mixing drugs like DXM and amphetamine. You will get serotonin syndrome and die, amphetamine has a MAOI effect slightly..even in OTC medical doses they are not to be consumed together, it has a warning on the fucking bottle warning against severe consequences. Again, drugs should be legal so that people have to use a bit of common sense about drug abuse, along with learning about what they are putting into their goddamned body to buy them, putting the illicit drug dealer out of business..
