Better off just getting a bottle of Robitussin Max Strength Cough. It's just DXM with inert ingredients.

And just drink it. Don't ever smoke DXM.
bhallg2k Reviewed by bhallg2k on . DXM Is it possible to derive the DXM from Robitussin DM? Is there a process that would give me something that is 100% DXM? If so, then what can I do with it? Smoke it? What? Please help Rating: 5
