Kratom, 7-OH laws diverge amid the spread of potent synthetic products

Traditional kratom has circulated for years as a lightly regulated herbal supplement, but concentrated 7-hydroxymitragynine, or 7-OH, products are now spreading alongside it, prompting 36 states to introduce regulation in the past two legislative sessions. At least 31 states already regulate kratom in some form, from outright bans to age limits and labeling rules, while Pennsylvania is weighing a bill to allow natural-leaf sales to adults 21 and up while banning concentrated 7-OH products.

U.S. poison centers logged 3,434 kratom-related exposure reports in 2025, about 1,200 percent more than in 2015, and 2026 is on pace to run 68 percent higher still. Physicians say 7-OH binds the same opioid receptor as morphine, making it more addictive and harder to quit, and note there is no quality control ensuring labels match contents.

The issue drew fresh attention in Mississippi after police found the same synthetic kratom product while investigating two university students' deaths, though toxicology results are pending and no link has been established. Researchers say the underlying poison-center data doesn't distinguish traditional leaf from newer concentrated formulations, limiting what can be concluded about actual risk.
