Dozens of U.S. states are suing Meta Platforms and its Instagram unit, accusing them of contributing to a youth mental health crisis through the addictive nature of their social media platforms.

In a complaint filed in the Oakland, California, federal court on Tuesday, 33 states including California and Illinois said Meta, which also operates Facebook, has repeatedly misled the public about the substantial dangers of its platforms and knowingly induced young children and teenagers into addictive and compulsive social media use.

“Research has shown that young people’s use of Meta’s social media platforms is associated with depression, anxiety, insomnia, interference with education and daily life, and many other negative outcomes,” the complaint said.

The lawsuit is the latest in a string of legal actions against social media companies on behalf of children and teens. ByteDance’s TikTok and Google’s YouTube are also the subjects of the hundreds of lawsuits filed on behalf of children and school districts about the addictiveness of social media.

“Meta has harnessed powerful and unprecedented technologies to entice, engage, and ultimately ensnare youth and teens,” the complaint said. “Its motive is profit.”

The lawsuit seeks a variety of remedies, including substantial civil penalties.
