The proposed bill establishes restrictions on the sale of over-the-counter diet pills and dietary supplements for weight loss or muscle building to individuals under 18 years of age in Washington State. It introduces a new chapter to Title 69 RCW, defining key terms such as "delivery sale," "delivery seller," and "dietary supplements for weight loss or muscle building." The bill prohibits any person from selling or giving away these products to minors and mandates that retail establishments verify the age of purchasers through valid identification. Additionally, it allows for the use of transaction scan devices to confirm age, while ensuring that the information collected is not misused.

Furthermore, the bill outlines the responsibilities of delivery sellers, including online retailers, who must ensure that any shipment of these products requires a signature from an adult and proof of age upon delivery. The Office of the Attorney General is empowered to investigate violations and enforce compliance, with penalties of up to $500 for most violations and up to $1,000 for specific infractions related to the misuse of transaction scan data. The bill emphasizes the importance of labeling and marketing practices, requiring courts to consider various factors when determining if a product is marketed for weight loss or muscle building.
