Attorney Advertising · Time-Sensitive
OpenClassActions.com is an attorney-advertising and informational resource — not a law firm. It does not provide legal advice and does not recommend or endorse any particular lawyer. Submitting a form on this page does not create an attorney-client relationship, file a lawsuit, or pause any legal deadline, and it does not guarantee that an attorney will review or respond to your case.
These claims are time-sensitive. Legal deadlines (statutes of limitations) vary by state and can permanently bar a claim once they pass — so don't wait for a callback. You are free to choose any attorney you wish, and if you are considering a claim you should speak with a qualified attorney of your choosing as soon as possible. Prior results do not guarantee a similar outcome.
Attorneys are investigating claims that Meta (Instagram, Facebook), ByteDance (TikTok), Google (YouTube) and Snap designed their platforms to be addictive and contributed to depression, anxiety, eating disorders and self-harm in teens. Families of teens diagnosed after heavy use may be eligible to have a case reviewed; as of October 2026 these are individual injury lawsuits in MDL 3047 and JCCP 5255, with no class settlement or claim form.

What the Surgeon General, APA, and CDC Have Said About Social Media and Youth Mental Health
The legal investigation does not exist in a vacuum. Three of the country’s most authoritative public-health voices have already published formal findings linking social media use to serious mental-health harm in adolescents.In May 2023, U.S. Surgeon General Dr. Vivek Murthy issued a formal Advisory titled Social Media and Youth Mental Health, warning that “there are ample indicators that social media can also have a profound risk of harm to the mental health and well-being of children and adolescents.” The Advisory called for urgent action from policymakers, technology companies, parents, and researchers, and specifically flagged the lack of adequate safety standards for minors on major platforms.
Also in May 2023, the American Psychological Association issued its Health Advisory on Social Media Use in Adolescence, a first-of-its-kind set of recommendations developed by its advisory panel of scientists. The APA found that social media use is “not inherently beneficial or harmful” to young people but cited strong evidence that specific design features — infinite scroll, algorithmic recommendation of harmful content, engagement-maximizing notifications, and social-comparison pressure — can cause significant harm to adolescents whose brains are still developing.
The Centers for Disease Control and Prevention’s Youth Risk Behavior Survey documents the scale of what parents have been experiencing: a sharp multi-year rise in adolescent depression, anxiety, self-harm, and suicidal ideation that tracks closely with the mass adoption of smartphones and social media. The CDC reported that in 2021 nearly 3 in 5 teen girls (57%) felt persistently sad or hopeless — the highest rate in a decade — and nearly 1 in 3 had seriously considered suicide.
Is Social Media Causing Depression and Anxiety in Teens?
Lawsuits against Meta, ByteDance, Google and Snap allege that Instagram, TikTok, Facebook, YouTube and Snapchat were designed to be addictive and contributed to depression, anxiety, eating disorders, self-harm and other mental health injuries in teens. Plaintiffs point to public-health advisories and to internal Meta research reported in 2021; the companies have not been found liable in most cases, and the first Los Angeles personal-injury verdict, in the K.G.M. case, is on appeal.As of October 9, 2026, new individual injury cases are still being filed into federal MDL 3047 and California’s JCCP 5255, and attorneys are still reviewing new cases from families whose child developed a diagnosed condition after heavy social media use. These are individual lawsuits, not a class action settlement, and no outcome is guaranteed.

How Social Media Affects the Teenage Brain
The teenage brain is uniquely vulnerable to the effects of social media. The prefrontal cortex — the region responsible for impulse control, decision-making, and emotional regulation — does not fully develop until the mid-20s. The lawsuits allege that social media platforms exploit this by delivering a constant stream of dopamine-triggering stimuli that adolescents are poorly equipped to resist.Research has shown that social media use in teens is associated with measurable changes in brain structure and function, including heightened sensitivity to social rewards (likes, comments, followers), reduced ability to regulate emotions and impulses, increased activation of brain regions associated with anxiety and fear, disrupted sleep architecture due to blue light exposure and pre-sleep scrolling, and diminished attention span and ability to concentrate on schoolwork.
Plaintiffs argue these effects alter how a young person’s brain develops during a critical period of growth.
The Instagram Eating Disorder Connection
In 2021, leaked internal Meta research was reported to show the company had found that Instagram made body image issues worse for one in three teenage girls. The lawsuits allege that Meta nonetheless continued to promote appearance-focused content and algorithmic recommendations that push teens toward increasingly extreme diet, fitness, and "thinspiration" content.The investigation alleges that Instagram's algorithm actively funnels vulnerable teens into rabbit holes of harmful content. A teenager who engages with one post about dieting may be shown dozens more about extreme weight loss, fasting, and pro-eating disorder content within hours. Plaintiffs link this algorithmic amplification to anorexia, bulimia, body dysmorphic disorder, and orthorexia among teen users.
Eating-disorder and body-image claims against Instagram are among those attorneys are still reviewing. See OCA’s social media eating disorder lawsuit page for who qualifies.
Social Media, Cyberbullying, and Teen Suicide
The alleged connection between social media and teen suicide is at the center of some of the most serious claims. Platforms like Instagram, TikTok, and Snapchat have been linked to cyberbullying, online harassment, and the algorithmic promotion of self-harm content. Unlike traditional bullying, cyberbullying follows children home — it is relentless, public, and permanent.Multiple families have filed lawsuits after losing children to suicide they allege was linked to social media. The lawsuits allege that platforms’ algorithms can actively recommend self-harm and suicide-related content to vulnerable teens, that platforms fail to remove dangerous content despite reports, that features like anonymous messaging and disappearing messages enable harassment, and that companies prioritize user engagement metrics over child safety.
The U.S. Surgeon General issued a formal advisory in 2023 warning that social media presents a "profound risk of harm" to children and adolescents, calling on tech companies to take immediate action to protect young users.
A newer front in this fight involves AI companion chatbots. Families have sued Character.AI and its part-owner Google after teens died by suicide following intense relationships with lifelike chatbots, and the first of those cases settled in early 2026. See our coverage of the Character.AI and Google teen chatbot harm lawsuits for how that litigation is unfolding.
Screen Time Addiction: How Platforms Keep Children Hooked
The lawsuits allege that social media companies use psychological techniques borrowed from the gambling industry to keep children on their screens. The features cited include infinite scroll designs that eliminate natural stopping points, autoplay features that keep content flowing without user action, push notifications engineered to create urgency and fear of missing out, variable reward systems (will this post get likes? how many?) that trigger dopamine loops, streak features on Snapchat that punish users for taking breaks, and algorithmic feeds that learn exactly what content will keep each individual user engaged the longest.The average American teenager now spends nearly five hours per day on social media. For many teens, this screen time comes at the expense of sleep, physical activity, face-to-face social interaction, and academic performance. The investigation alleges that social media companies designed these addictive features knowing they would disproportionately affect children and teens.
What Social Media Dangers Should Parents Know About?
Beyond addiction and mental health harm, social media platforms expose children to a range of dangers including predatory contact from adults who use platforms to groom minors, exposure to age-inappropriate content including violence, sexual material, and drug use, dangerous viral challenges that have caused serious injuries and deaths, sextortion schemes targeting teens through platforms like Instagram and Snapchat, comparison culture that damages self-esteem and creates unrealistic expectations, and sleep disruption from late-night scrolling that affects academic performance and physical health.The investigation alleges that social media companies were aware of these dangers and failed to implement adequate safeguards, parental controls, or age verification systems to protect minors.
Who Qualifies for the Teen Mental Health Social Media Lawsuit?
Claims under review generally involve a child or teenager who used Instagram, TikTok, Facebook, YouTube or Snapchat heavily and then developed a diagnosed or treated condition such as depression or persistent sadness, anxiety or panic attacks, an eating disorder (anorexia, bulimia, body dysmorphia), self-harm or suicidal thoughts, social media addiction or compulsive use, sleep disorders or chronic sleep deprivation, or another mental health condition the family links to social media use. Cyberbullying, academic decline and social withdrawal are often part of the history in these cases.Parents and legal guardians typically bring claims on behalf of minor children, and adults who were minors during the period of heavy use may also have claims reviewed. Exact criteria are set by the reviewing attorneys, and statutes of limitations vary by state.
Where the Litigation Stands: October 2026 Update
• MDL 3047. The federal multidistrict litigation before Chief Judge Yvonne Gonzalez Rogers in the Northern District of California had 3,824 pending actions in the Judicial Panel on Multidistrict Litigation’s October 1, 2026 report, up from 3,208 on September 1, 2026. Families join through the court’s Master Short-Form Complaint, and short-form complaints were still being filed in October 2026. The next school-district bellwethers (Tucson Unified and Charleston County) are set for February 2027.• JCCP 5255. In Los Angeles Superior Court, Judge Carolyn B. Kuhl consolidated two teen plaintiffs’ cases for one jury trial set to begin October 28, 2026 against Meta, YouTube and Snap; TikTok settled with both plaintiffs in August 2026. The first trial, the K.G.M. case, ended March 25, 2026 with a $6 million verdict against Meta and YouTube that is now on appeal.
• Meta and the states. Meta’s consent judgment with the states was entered August 26, 2026: about $12.1 billion guaranteed to states over 10 years, up to $17.1 billion in total, plus product changes for users under 18. It pays states, not families, has no claim form and does not release any individual injury claim. See OCA’s coverage of the Meta state settlement and the teen account changes it requires.
• TikTok and Alabama. In late September 2026, days before a scheduled trial, Alabama reached the first state settlement with TikTok and ByteDance over teen-safety claims — at least $100 million to the state, rising up to $300 million if 40 other attorneys general sign similar agreements in time, plus a two-hour daily limit, pauses after 15 minutes of use and stricter age checks for teens in Alabama. TikTok did not admit wrongdoing, and the money goes to the state.
How Much Compensation Is Available?
There is no class settlement or set payout. Individual compensation depends on the severity of harm, the platforms involved and the facts of each case, and no amount is guaranteed. In the related litigation, TikTok and Snap have settled some individual cases on undisclosed terms, the $6 million K.G.M. verdict is on appeal, and the first federal bellwether — a Kentucky school district, Breathitt County — settled for a combined $27 million in May 2026.Damages claimed in individual cases can include therapy and medical treatment costs, lost income or educational setbacks, pain and suffering, emotional distress, and out-of-pocket expenses related to the harm.
How a Free Case Evaluation Works
Attorneys are still reviewing new cases and offer free, no-obligation evaluations. A family completes the evaluation; where the facts may qualify, the family can be connected with an attorney who handles social media harm cases, typically on a contingency basis. Submitting an evaluation does not guarantee that a lawsuit will be filed or that any compensation will be recovered.Free Case Evaluation — See If Your Family Qualifies
Frequently Asked Questions
What is the October 2026 update on the teen mental health social media lawsuits?
As of October 9, 2026, new individual injury cases are still being filed into federal MDL 3047 and California's JCCP 5255, and attorneys are still reviewing new cases. MDL 3047 had 3,824 pending actions in the Judicial Panel on Multidistrict Litigation's October 1, 2026 report, the next Los Angeles personal-injury trial is set to begin October 28, 2026 against Meta, YouTube and Snap, and the $6 million K.G.M. verdict against Meta and YouTube is on appeal.
Does Meta's $17.1 billion state settlement pay families of harmed teens?
No. Meta's consent judgment with the states, entered August 26, 2026, guarantees about $12.1 billion to states over 10 years, up to $17.1 billion in total, and requires product changes for users under 18. The money goes to states, not families; there is no claim form, and the judgment does not release any individual injury claim.
Is social media really causing depression in teens?
Public-health authorities, including the U.S. Surgeon General in a 2023 advisory, have warned that social media can pose a profound risk of harm to youth mental health, and lawsuits allege that Instagram, TikTok, YouTube and Snapchat were designed in ways that contributed to depression, anxiety, eating disorders and suicidal ideation in teens. Whether a platform caused a particular teen's injury is decided case by case; in the first Los Angeles trial, the K.G.M. case, a jury found Meta and YouTube negligent, and that verdict is on appeal.
How does social media affect a teenager's brain?
Lawsuits allege that social media platforms are designed to exploit the developing adolescent brain by triggering dopamine responses through likes, comments, and algorithmic content feeds. Teens may be especially vulnerable because the prefrontal cortex, which controls impulse regulation, is not fully developed until the mid-20s, which researchers say can make teens more susceptible to compulsive use, social comparison, and emotional harm from cyberbullying and toxic content.
Can I sue Instagram for my teenager's eating disorder?
Families have filed individual lawsuits against Meta alleging that Instagram promoted content that contributed to eating disorders in teens, and plaintiffs cite internal Meta research reported in 2021 about Instagram and teen girls' body image. These claims generally involve heavy Instagram use followed by a diagnosis of, or treatment for, anorexia, bulimia or body dysmorphia. Attorneys are still reviewing new cases; whether a claim qualifies depends on its facts and on each state's statute of limitations.
What can parents do about social media harming their children?
Parents of children harmed by social media have filed individual personal-injury and wrongful-death lawsuits in MDL 3047 and JCCP 5255, and attorneys offer free case evaluations to families whose child developed depression, anxiety, an eating disorder, self-harm or another diagnosed condition after heavy use. These individual cases are not part of a class settlement, and there is no claim form.
Is there a connection between social media and teen suicide?
Research has shown a correlation between heavy social media use and increased rates of suicidal ideation and self-harm among teens. Platforms have been accused of algorithmically amplifying harmful content, including content related to self-harm and suicide. Multiple lawsuits have been filed by families who lost children to suicide they allege was linked to social media exposure.
Does screen time addiction in children qualify for a lawsuit?
The lawsuits allege that social media companies deliberately designed their platforms to be addictive to young users without adequate safety measures. Claims generally center on compulsive use followed by a diagnosed injury — such as depression, anxiety, an eating disorder, self-harm or serious sleep disruption — rather than screen time alone. Exact criteria are set by the reviewing attorneys.
