The state poison center is starting to get calls about a dangerous new synthetic drug called 2C-E.
The effects are similar to ecstasy or LSD and overdose symptoms include agitation, paranoia, violence, and high heart rate.
One overdose victim was found running naked around a lake.
There have been no deaths in Illinois, but 2C-E overdoses have killed people in other states.
As the deadly epidemic spiraled out of control several weeks ago, a young specialist in infectious disease control working at the Illinois Department of Public Health volunteered to fly to the front line of the fight.
