The bill prohibits the targeted advertisement and promotion of vapor products to individuals under the age of 21 on social media platforms. It establishes that it is unlawful for any person to engage in such advertising practices, specifically targeting this age group. The bill defines "vapor product" broadly to include devices like e-cigarettes and vape pens, as well as any components or substances associated with these devices, while excluding FDA-approved products. Additionally, it defines "social media platform" to encompass public or semi-public internet services that facilitate social interactions among users.

Violators of this law will face civil penalties of up to $250,000 per violation, which can be enforced through civil action under the "Penalty Enforcement Law of 1999." The Superior Court and municipal courts are granted jurisdiction to handle these enforcement actions. The bill is set to take effect immediately upon passage.
