Is Social Media Addiction Real?

Two years ago, US Surgeon General Vivek Murthy, MD, called for warning labels on social media platforms, citing concerns about the potential mental health risks associated with heavy use, especially among children, adolescents, and young adults.

The debate has intensified as researchers investigate how heavy social media use affects brain development, mood, and cognition and whether patterns of heavy social media use resemble behavioral addictions.

That scrutiny reached a turning point on March 25, when a Los Angeles jury found Meta and Google liable in a landmark case, concluding that the companies' platforms were negligently designed and contributed to a young user’s mental health harms.

The verdict, which is reportedly the first of its kind, could shape thousands of similar lawsuits alleging that social media companies knowingly engineered addictive products.

Why the Hype?

Concerns about social media addiction have grown along with rising rates of anxiety, depression, and suicidal behavior among young people. Recent research suggests that it may not be total screen time that matters most but patterns of addictive use.

For example, a large longitudinal cohort study that tracked more than 4000 US adolescents for 4 years found that about 31% developed increasing trajectories of addictive social media use beginning around age 11, and those with high or increasing addictive use had more than double the risk for suicidal behaviors or ideation compared with peers with low addictive use.

However, baseline screen time alone did not predict mental health outcomes. Instead, behaviors associated with addiction such as compulsive checking or distress when unable to use social media were more strongly linked to adverse outcomes.

“What matters clinically is that simply spending more time on screens at age 10 was not associated with worse suicide-related and mental health outcomes; it was the addictive use patterns that predicted risk,” Yunyu Xiao, PhD, assistant professor, Department of Psychiatry and Population Health Sciences, Weill Cornell Medicine/NewYork-Presbyterian, who led the study, told Medscape Medical News.

Yet, in another large cohort study of adolescents, time spent on social media did seem to matter. Researchers found that spending more than 3 hours per day on social media was associated with an increased risk of reporting high levels of internalizing and externalizing problems, even after adjusting for mental health problems.

A separate study showed that a 1-week social media “detox” intervention among young adults was associated with significant reductions in symptoms of depression, anxiety, and insomnia.

How Does Social Media Use Affect the Developing Brain?

Social media platforms are built around intermittent rewards likes, comments, notifications that activate the brain’s reward system. Research suggests that these cues stimulate dopamine release in neural circuits involved in motivation and reinforcement, similar to mechanisms seen in other behavioral addictions.

“Social media activates the same reward pathway as drugs and alcohol, releasing dopamine in the nucleus accumbens and creating neural networks that constitute the habit loops that have us clicking, checking, scrolling, and swiping, far beyond what’s healthy or even what we want,” Anna Lembke, MD, professor of psychiatry and addiction medicine, Stanford University School of Medicine, California, and author of Dopamine Nation, told Medscape Medical News.

At the cellular level, said Lembke, the youth brain is a “vulnerable brain because from age 5 to age 25, we’re cutting back on the neurons we’re not using and myelinating the neurons we use most often.

“Hence, early exposure to addictive substances and behaviors fosters a neurological scaffolding built upon these unhealthy habit loops. The earlier a child is exposed to social media, the more likely they are to get addicted to social media.”

Is It Really an Addiction?

Despite growing concern, social media addiction is not currently recognized in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision (DSM-5-TR).

There is disagreement about whether problematic social media use constitutes a distinct addiction or whether it should be classified under broader categories such as internet addiction, behavioral addictions similar to gambling disorder, or compulsive digital media use.

Some experts argue that many patterns of heavy use resemble behavioral addictions, with key features such as loss of control over use, continued use despite negative consequences, withdrawal-like symptoms (irritability when unable to access platforms), and increasing time spent using the platform.

Others caution that labeling excessive use as “addiction” may oversimplify a complex behavioral phenomenon, noting that problematic social media use may reflect coping strategies or underlying conditions rather than true addiction.

Lembke said she is “decidedly in the camp that views social media as addictive for some users, with behavior patterns that mirror those seen in other addictions.” She added that, in her view, what is often called social media addiction referred to more formally as “social media use disorder” probably will be incorporated into future diagnostic frameworks such as the DSM and ICD-11.

She expects it would fall under substance-related and addictive disorders, alongside conditions like gambling or gaming disorder, and be defined using the same core criteria which she described as the “Four C’s” loss of control, compulsive use, craving, and continued use despite consequences with tolerance and withdrawal considered optional.

“In other words,” said Lembke, “it makes the most sense to build on existing categories and definitions of addiction when talking about social media addiction. Although there may be some nuanced differences between social media addiction and say, internet gaming disorder, there are more similarities than differences.”

Xiao said that whether it is ultimately classified as a standalone addiction or a subtype of behavioral addiction, the empirical evidence is clear. “These compulsive use patterns follow addiction-like trajectories; they are measurable, escalate over time in substantial subgroups, and are associated with significant mental health consequences,” he said.

Can Social Media Be Positive?

Despite concerns, social media can also offer meaningful benefits to young people. Studies have shown that online platforms can help adolescents maintain friendships and social support networks, provide access to mental health resources and peer communities, and help marginalized groups to find identity affirmation and social connection.

However, experts agree that the relationship between social media use and mental health is complex and highly individualized, with both risks and benefits depending on patterns of use and personal vulnerabilities.

For adolescents, open family discussions about online behavior and expectations can help establish healthy habits. Encouraging balanced, intentional social media use such as setting screen-free times during meals or before bedtime, for example; turning off nonessential notifications; prioritizing active engagement over passive scrolling; and paying attention to emotional responses to online interactions can also help keep social media use positive.

How Do Clinicians Identify At-Risk Patients?

Clinicians increasingly face questions from patients and parents about whether problematic social media use constitutes an addiction and how to recognize and treat it.

“Clinicians need to screen patients for social media addiction the same way they would for any addiction; that is, ask patients what digital media platforms they use, how much and how often, and then ask about the Four C’s, tolerance, and withdrawal,” said Lembke.

Several validated instruments may help clinicians assess problematic use. They include the Social Media Disorder (SMD) Scale, a nine-item scale that measures problematic social media use among adolescents.

There is also the Bergen Social Media Addiction Scale (BSMAS), a self-report questionnaire designed to measure dependence on social media, as well as the Digital Media Overuse Scale (dMOS) which assesses broader patterns of problematic digital engagement.

While these scales are not diagnostic, they can help identify patients who may benefit from behavioral interventions, Lembke noted.

Xiao noted that children who initially show low or moderate levels of addictive social media use are not typically considered at risk. However, ongoing follow-up can help identify concerning trends, such as progression to more severe patterns of use over time.

“Clinicians should consider repeated, longitudinal screening for addictive use patterns, not just a one-time snapshot, particularly during the transition into adolescence,” Xiao advised.

Who Is at Greatest Risk?

Females are more likely to have high or increasing addictive use of social media and mobile phones, while males are more likely to show high addictive use of video games.

Critically, said Xiao, disparities extend beyond overall use. Youth who are Black or Hispanic, from lower-income or less-educated households, or who have unmarried parents were more likely to follow high addictive-use trajectories a pattern consistent with broader childhood developmental outcomes influenced by social determinants of health.

“Factors like exposure to racism and adverse childhood experiences can make children from underserved communities more susceptible to these adverse outcomes,” Xiao added.
