It's an herbal supplement you can buy at the store and it's now being linked to two Chester County deaths. It's called "kratom." People are using it in place of opioids.

What to Know At least two men in Chester County, Pennsylvania, died this year after taking kratom, a legal herbal supplement.

Kratom has sparked debate regarding its safety, with supporters citing its benefits in treating pain and opioid addictions.

The FDA warns its dangerous and isn't a better alternative to prescription opiates.

At least two men in Chester County, Pennsylvania, recently died after taking a legal herbal supplement often used to treat opioid addiction and other medical issues, the coroner’s office said.

Caleb Jonathan Sturgis of West Bradford Township died in June from acute mitragynine intoxication after ingesting the botanical supplement kratom. Ryan Jones of Caln Township died in April also after taking kratom. Both overdoses appeared to be accidental, according to the Chester County Coroner’s Office.

Mitragyna speciosa, commonly known as kratom, is a plant that grows naturally in Thailand, Malaysia, Indonesia and Papua New Guinea, according to the FDA.

Kratom affects the same opioid brain receptors as morphine and appears to have properties that expose users to the risks of addiction, abuse and dependence. There are no FDA-approved uses for kratom, and the agency has received concerning reports about its safety.

“Given the opioid addiction crisis, it would seem preposterous that an opioid is legal for use in the United States and can be purchased at tea stores, convenience stores, over the internet and, yes, even from vending machines,” FDA Commissioner Scott Gottlieb, M.D., wrote in a statement. “However, kratom is not your average opioid.”

Gottlieb said the Drug Enforcement Agency tried to ban the herb in 2016 but dropped its attempt after public outcry from users as well as 51 congressmen around the country and across the political aisle. Some of its supporters argued it could be an alternative to drugs like OxyContin.

Jon Wilt sells kratom at his West Chester, Pennsylvania, smoke shop Planet Ryo. Wilt told NBC10 he constantly hears success stories about kratom from customers who take it for various reasons, including pain relief, migraines and issues with focusing.

“I’ll take it for pain relief but it doesn’t get me high,” one customer, who did not want to be identified, told NBC10.

According to Wilt however, the biggest reason his customers normally give him is because they believe kratom is safer than the opiates a doctor might prescribe for their pain.

“Big time for getting off opiates or they don’t want to go on them,” Wilt said. “That is the biggest thing with kratom.”

In a February memo, the FDA insisted there’s no evidence that those advantages exist for kratom and they warn it can be dangerous. FDA officials say it’s addictive, isn’t a better alternative to prescription opiates, shouldn’t be used and definitely shouldn’t be mixed with other drugs.

Dr. Jason Wallach, who teaches pharmaceutical science at the University of the Sciences, believes there should be more clinical trials conducted on kratom before a decision is made about its legality.

“It’s safer than many alternatives,” Dr. Wallach said.

Wallach also said there needs to be better oversight of the kratom products coming into the country unregulated.

“You don’t always know what you’re getting,” he said. “There have been incidents where kratom has been adulterated with synthetic opioids.”

Kratom is available without a prescription in many parts of the country. Its use is banned in Alabama, Arkansas, Indiana, Rhode Island, Tennessee, Vermont, Washington, D.C., Wisconsin and Louisiana however.

Kratom is legal in Pennsylvania and Delaware while there is pending legislation on it in New Jersey.
