The Illinois Department of Public Health is warning people about a severe bleeding condition caused by synthetic pot.
There have been four cases of the condition -- caused by a vitamin k-dependent coagulopathy -- which reduces the blood's ability to clot. All four people had to be hospitalized.
They were reported to the Illinois Poison Center on March 10.
All four individuals have reported using synthetic cannabinoids, commonly referred to as fake pot, Spice, K2, and Mind Trip. The health effects from using synthetic cannabinoids can be unpredictable and harmful -- even life threatening.
Anyone who has a serious reaction to synthetic cannabinoids should call 911 or go to the emergency department immediately.
