Health officials have issued another warning regarding synthetic marijuana, also known as "spice" or "K2."
The Centers for Disease Control and Prevention report that hospitalizations from the drugs are on the rise.
Chemical modifications in "spice" can make it up to a hundred times more potent than marijuana, officials say.
The synthetic drug can cause strokes, seizures, kidney damage and even death.
Doctors do not have an antidote for overdoses.
