TV 6 reports that a synthetic drug has sent some people in mid-Michigan to the hospital.

"Darth Vapor" is the drug in question, which is also the name of an e-liquid produced by an e-cigarette company; the problem with this form of "Darth Vapor" is that while it mimics the effects of marijuana, it has sent some people to the hospital.  It can cause seizures, heart failure and other ill effects.
