Six US states have banned the sale and use of the Kratom, a psychoactive plant-derived drug from Southeast Asia that is available online and in head shops. Researchers studying kratom have found that it affects brain receptors for strong opioids.

A new study provides some data to support those states’ concerns (J. Am. Chem. Soc. 2016, DOI: 10.1021/jacs.6b00360).
