'Smiles' can be deadly. That's a warning from doctors about a new type of designer drug that's finding its way to teenagers.

FOX News Radio's Pat O'Neill has more in today's edition of "Housecall For Health":

A new line of illegal synthetic drugs is responsible for the deaths of two U.S. teens. The drug, nicknamed 'smiles' is a hallucinogen that doctors at Johns Hopkins say there is very little information about. It is sold in powder form and mixed with candy or chocolate before ingesting. Experts believe smiles increases heart rate, and can cause fatal heart arrhythmias. Both deaths occurred in North Dakota, but it's not clear how widespread the drug is.
