The Centers for Disease Control says the the number of overdose deaths from the herbal supplement kratom are more common than previously reported.
In a report released yesterday, the CDC stated that kratom was a cause in 91 deaths in 27 states.
Most of the people in those overdose deaths had also taken other drugs like heroin and fentanyl, but in seven of them kratom was the only detected substance.
Kratom comes from a plant that's native to south-east asia and is sold in capsules.
Makers of the supplement claim it eases pain, anxiety, and drug dependence.
CDC officials say it causes euphoric effects similar to opioids.
