Over-the-counter cold and cough medicines containing the drug Dextromethorphan (DXM) have also been abused. DXM is sold in syrup, gel and tablet form. When sold on the Internet as powder, it is particularly risky because of the uncertainty of its composition and dose. It is found in more than 100 products; Coricidin and Robitussin are abused the most.
