Prohibits social media platforms from using certain practices or features that cause child users to become addicted to platform.

This bill prohibits social media platforms from using features or practices that cause addiction among users under 18 years old. It defines addiction as compulsive use that leads to physical, mental, emotional, developmental, or material harm, and requires platforms to conduct regular audits to identify and fix addictive design elements within 30 days. The law exempts small businesses with less than $100 million in revenue and video game platforms from these requirements, while protecting platforms from liability for user-generated content and existing federal or state protections. Violations could result in civil penalties of up to $250,000 per incident enforced through New Jersey's existing penalty enforcement procedures.
