The families of four teenagers who died by suicide are suing Meta, Snapchat, TikTok and YouTube, alleging that using the social media platforms led to severe mental health and physical issues that resulted in their deaths. The Social Media Victims Law Center, a legal advocacy firm, filed the complaint on behalf of the four families, who are from Minnesota, North Carolina, Tennessee and Texas. Meta, Snapchat, TikTok and YouTube parent company Google did not immediately respond to a request for comment. Thursday's complaint represents the latest in a series of suits filed against social media companies alleging that they are addictive and dangerous.
