For example, in 2010, nine people died due to the combination of O-desmethyltramadol, a μ-opioid agonist and analgesic drug, and kratom, an Asiatic medicinal plant containing mitragynine, another μ-opioid agonist, in a synthetic cannabinoid product called "Krypton". [38] And in 2013, AH-7921 was detected in smoking blends in Japan. [39]
Mitragynine is an indole-based alkaloid and is one of the main psychoactive constituents in the Southeast Asian plant Mitragyna speciosa, commonly known as kratom. [4] It is an opioid that is typically consumed as a part of kratom for its pain-relieving and euphoric effects.
The FDA tested 30 different kratom products in 2019 and found "significant levels" of lead and nickel in them, which researchers said could cause heavy metal poisoning if consumed over the long term.

7-Hydroxymitragynine (7-OH) is a terpenoid indole alkaloid from the plant Mitragyna speciosa, commonly known as kratom. [2] It was first described in 1994 [3] and is a human metabolite metabolized from mitragynine present in the Mitragyna speciosa. 7-OH binds to opioid receptors like mitragynine, but research suggests that 7-OH binds with greater efficacy.
