Also, cough syrups just happens to be the most common sourse of DXM. You can also get pure-DXM powder or pills that contain a recreational amount already in them. I happen to enjoy the effects of DXM, and I usually don't feel like ordering a pure powder online when I can easily buy some Tussin from Jewel. The only bad thing about syrup is all the glucose in it, which puts a strain on your pancrease (the organ that regulates insulin, in case you didn't know). But so does eating a large peice of buttercream cake.
