Adolescent Mental Health and Substance Use: 2024 Trends and Access to Care

A landmark legal battle, K.G.M. V. Meta Platforms, Inc. Et al., recently highlighted a growing crisis: a jury held major social media platforms responsible for the mental health harm of an adolescent, citing addictive design features. This case is more than a legal precedent. it’s a reflection of a broader struggle facing today’s youth. From the pressure of heavy screen time and social media use to the trauma of gun violence and chronic sleep deprivation, adolescents are navigating a complex landscape that frequently leads to anxiety, depression, and substance use.

While some recent data shows modest improvements in certain areas, the overall picture remains concerning. Suicide rates, though slowly declining, are higher than they were a decade ago, and the opioid epidemic continues to cast a long shadow over teen health. Understanding these trends and the systemic barriers to care is essential for supporting the next generation.

The Current State of Adolescent Mental Health

Mental health struggles among adolescents have reached a critical point, though the trajectory varies by condition. According to 2024 data, anxiety has emerged as the most common mental health condition in this population.

Depression and Anxiety Trends

• Major Depressive Episodes (MDE): In 2024, 15% of adolescents (approximately 3.8 million) reported a past-year MDE. This is a decrease from the 21% reported in 2021 during the pandemic.
• Anxiety: Roughly 19% of adolescents (4.9 million) reported moderate to severe symptoms of anxiety in 2024. While trend data for anxiety is limited, other surveys indicate that diagnosed anxiety has increased and remains above pre-pandemic levels.
• Feelings of Hopelessness: A survey of high school students revealed that those reporting feelings of sadness and hopelessness—key indicators of depressive disorder—rose from 30% in 2013 to a peak of 42% in 2021, settling at 40% in 2023.

Substance Use Disorder (SUD)

Substance use remains a significant challenge, though there’s a slight downward trend. In 2024, 7.8% (2 million) of adolescents reported having a substance use disorder in the past year, compared to 9.2% in 2021. This aligns with findings that drug and alcohol use among high school students declined slightly between 2017 and 2023, even as overdose deaths spiked during the pandemic years.

The Cycle of Co-occurrence: Mental Health and Drugs

There’s a powerful link between poor mental health and substance use. Many adolescents don’t use drugs in a vacuum; they use them to manage untreated psychological pain.

Data from 2024 shows that illicit drug use is significantly more prevalent among those struggling with mental health:

• MDE: 33% of adolescents with a past-year MDE used illicit drugs, compared to only 12% of those without.
• Anxiety: 26% of adolescents with anxiety symptoms used illicit drugs, compared to 10% without.

In a CDC convenience sample of teens (ages 13 to 18) who used substances in the last 30 days, 40% admitted they used those substances to cope with anxiety or depression. Marijuana use is particularly common in this group, with 25% of those with an MDE and 18% of those with moderate to severe anxiety using the drug. This is concerning because marijuana—and specifically the compound THC—is linked to the onset of psychotic disorders, including schizophrenia, especially with frequent use.

Suicide and Overdose: The Deadliest Outcomes

The most severe consequences of the youth mental health crisis are suicide and drug overdoses. While some numbers are moving in the right direction, the totals remain alarmingly high.

Suicide Trends

Adolescent suicide deaths peaked in 2018 with 1,750 deaths. By 2024, that number declined to 1,478, representing a 5% decrease from 2023. However, these deaths are more prevalent among males and are increasing more rapidly for adolescents of color than for their White peers. While males have higher death rates, females report higher rates of serious suicidal thoughts.

Method of death is also a critical factor: over 4 in 10 of the more than 17,000 adolescent suicides over the last decade involved a firearm. Access to firearms in the home remains a primary risk factor.

The Fentanyl Crisis and Overdose Deaths

Drug overdose deaths among adolescents more than doubled during the COVID-19 pandemic, driven largely by fentanyl—a potent synthetic opioid. Opioid-related deaths jumped from 165 in 2019 to 396 in 2020.

There is a glimmer of hope: opioid-related deaths dropped sharply from 557 in 2023 to 272 in 2024. This decline is likely due to increased public awareness, better fentanyl detection, and school-based initiatives. For the 2024-2025 school year, 77% of public schools stored naloxone (a nasal spray to reverse overdoses) and 52% provided fentanyl education.

Barriers to Care and the Impact of Policy

Access to behavioral health services is inconsistent. While 60% of adolescents with an MDE received treatment in 2024—including telehealth (33%) and prescription medication (31%)—those with substance use disorders are far less likely to get help. Only 30% of the 2.4 million adolescents in need of substance use care received treatment in 2024.

The Role of Insurance and Medicaid

Medicaid is a lifeline for youth mental health, providing coverage for nearly 40% of children and teens. Through the Early and Periodic Screening, Diagnostic and Treatment (EPSDT) benefit, Medicaid ensures medically necessary services are covered with low out-of-pocket costs.

Policy Shifts and Funding Risks

Recent administrative changes have created uncertainty for youth services:

• Bipartisan Safer Communities Act (BSCA): Originally passed in 2022 to strengthen school-based mental health services, funding for these programs has been disrupted under the second Trump Administration.
• SAMHSA and 988: The Substance Abuse and Mental Health Services Administration (SAMHSA) oversees the 988 crisis hotline, which has been linked to lower adolescent suicide rates. However, funding for 988 remains flat for 2027, and a specialized extension line for LGBTQ individuals—a group more prone to suicidality—has been removed.
• Treatment Gaps: A lack of adolescent-specific residential addiction facilities and limited access to buprenorphine continue to hinder recovery for youth with opioid use disorders.

Frequently Asked Questions

Why is marijuana use a concern for adolescents with anxiety or depression?

While some may use it to self-medicate, marijuana use in youth is linked to the earlier onset of psychosis and an increased risk of schizophrenia. The rising levels of THC in marijuana further increase the risk of psychotic symptoms.

How does the 988 hotline help adolescents?

The 988 crisis hotline provides immediate support for those in suicidal or mental health crises. Research has linked the service to a decrease in adolescent suicide mortality, making stable funding and inclusive services (such as those for LGBTQ youth) critical.

What is the “EPSDT” benefit in Medicaid?

Early and Periodic Screening, Diagnostic and Treatment (EPSDT) is a Medicaid benefit that requires the coverage of any medically necessary health care service to correct or ameliorate a condition that could jeopardize the health or development of a child.

Looking Forward

The decline in adolescent overdose deaths and the modest drop in major depressive episodes suggest that intervention strategies are working. However, the fragility of school-based funding and the persistence of high suicide rates among adolescents of color and LGBTQ youth show that the work is far from over. To sustain these gains, the focus must shift toward stabilizing funding for crisis services and removing the structural barriers that prevent 70% of adolescents with substance use disorders from receiving the care they need.
