The Connection Between Mental Health & Substance Abuse in Teens
Did you know that teens struggling with poor mental health are at an increased risk for abusing substances? It’s estimated that 60-75% of adolescents with a substance use disorder also have a co-occurring mental health condition.
Anxiety, depression, PTSD, and ADHD frequently drive teens to self-medicate, seeking relief from overwhelming emotions. But instead of solving the problem, substance use makes it worse—deepening feelings of despair, increasing impulsivity, and leading to habit-forming addictions.

Seeking Self-Medication
For many teens, what starts as curious experimentation with drugs or alcohol can quickly turn into self-medication. For example, a teen struggling with anxiety might feel relief with the numbing effects of alcohol. Or a teen stuck in depression might feel an exhilarating escape when using stimulants.
The problem is that self-medicating doesn’t treat the root issue; it only masks the symptoms. While substances may provide short-term relief, they often worsen mental health over time. Even worse, with continued use, teens develop drug-tolerance, requiring larger doses to achieve desired effects eventually leading to dependence or addiction.
More than 21.5 million people in the US struggle with co-occurring substance abuse and mental illness–an addiction that often begins in adolescence.

The Neurochemical Connection
Often, the link between substance abuse and mental health is about more than seeking a way to self-medicate an existing problem. Both mental health disorders and substance abuse impact dopamine and serotonin systems–the brain’s key neurotransmitters responsible for mood regulation, pleasure, and motivation.
When a teen experiences joy—whether from social interactions, hobbies, or achievements—the brain releases dopamine. Drugs and alcohol artificially trigger large dopamine surges, creating an intense but unnatural sense of pleasure.
Over time, this floods the brain’s reward circuits, reducing natural dopamine production and making everyday joys like spending time with family or achieving personal goals feel dull in comparison. This can lead to worsening depression.
Chemically, this compounds the depression problem. A teen suffering from depression already has low serotonin levels, leading to erratic mood swings and emotional instability. Substance use further depletes serotonin, worsening symptoms. This in turn leads to an increased risk of self-harm or suicidal behaviors.

Genetic and Environmental Factors Influencing Teen Substance Use and Poor Mental Health
Genetics play a role in shaping a teen’s risk for both mental health disorders and substance abuse. Research suggests that 40-60% of a person’s susceptibility to addiction may be inherited.
Depression, anxiety, bipolar disorder, and ADHD all have strong genetic components. But that’s just one piece of the puzzle. Environmental factors, like adverse early childhood experiences, past trauma, and family instability play a role as well.
Common Risk Factors Include:
- Family History
- Neurochemical Imbalances
- Developmental Brain Changes
- Chronic Health Conditions (e.g. Chronic Pain)
- Early Exposure to Drugs or Alcohol (Normalized Behavior)
- Social Media and Peer Influence
- Too Much Idle Time with Low Supervision
- BrFamily Dysfunction (Divorce, Parental Substance Abuse)
- Bullying
- Academic Stress or Failure
- Lack of Identity
- Lack of Positive Role Models

Breaking the Cycle of Poor Mental Health & Substance Abuse
It’s clear that these issues do not exist in isolation. Teens often turn to drugs or alcohol in an attempt to self-medicate their emotional pain, but rather than finding relief, they fall deeper into a destructive cycle of addiction, worsening mental health, and dependence.
Early intervention is the key to stopping the spiral and achieving long-term, sustainable recovery with co-occurring substance abuse and mental health struggles.
