The New Jersey Kratom Consumer Protection Act aims to regulate the sale and distribution of kratom products, defined as those containing the alkaloid mitragynine from the Mitragyna speciosa plant. The bill mandates that kratom retailers must disclose on product labels that the item is a kratom product and provide factual information regarding its contents. It prohibits the sale of kratom products that are adulterated or contaminated with dangerous non-kratom substances, exceed specified levels of 7-hydroxymitragynine, contain synthetic alkaloids, or lack proper labeling regarding their alkaloid content. Retailers are also restricted from selling kratom products to individuals under 21 years of age, with penalties for violations including civil fines and potential criminal charges.

The Department of Health is tasked with establishing rules for the administration and enforcement of the act, including safety testing standards and product registration fees. Retailers found in violation of the labeling and product safety requirements face escalating penalties, with a third violation resulting in a three-year prohibition on selling kratom products. The act also allows for private causes of action for individuals harmed by violations and requires the Department of Health to conduct a study on the health effects of kratom, reporting findings to the Governor within a year of the act's enactment.
