The bill amends Chapter 270 of the General Laws to establish regulations for the sale of kratom products in the Commonwealth. It defines key terms such as "kratom product," "kratom retailer," and "manufacture," and outlines specific labeling requirements for kratom products. Retailers must provide clear labels that include the manufacturer's name and address, a complete list of ingredients, and directions for safe use. Additionally, the bill prohibits the sale of adulterated or contaminated kratom products, those containing excessive levels of 7-hydroxymitragynine, or any synthetic alkaloids. It also sets the legal age for purchasing kratom products at 21 years.

Violations of these regulations can result in administrative fines, with penalties increasing for repeat offenses. The bill stipulates that a retailer may defend against violations if they can demonstrate reliance on the manufacturer's compliance. Furthermore, the Department of Public Health is tasked with creating rules and regulations for the enforcement of these provisions, including standards for labeling and safety testing of kratom products. The act will take effect 180 days after its passage.
