A new Illinois law makes it illegal to sell, possess, deliver, or distribute dextromethorphan (DXM), a key ingredient in many over-the-counter cough medicines that also can be used to get high, the Chicago Tribune reported May 26.

The law, signed by Gov. Rod Blagojevich last week, seeks to curb abuse of the main active ingredient in cough medicines like Robitussin. Known as "skittles," "robo" or "triple C" among users, pure DXM can be bought online and elsewhere and used for its hallucinogenic effects. Misuse of the drug can cause confusion, dizziness, vomiting, and increased heart rate.

"The idea that kids can go online and easily get their hands on a dangerous drug is appalling," Blagojevich said.
