Adverse Childhood Experiences: Understanding the Impact and Creating a Path Toward Healing

Childhood is ideally a time of safety, learning, and connection. Yet for many children, early years are marked by instability, overwhelming stress, or trauma. These moments—known as Adverse Childhood Experiences, or ACEs—can shape health, emotions, and life opportunities well into adulthood. By understanding what ACEs are and how they influence development, we can work together to build safer, more nurturing environments where children can thrive.

What Are ACEs?

Adverse Childhood Experiences include a range of potentially traumatic events that occur before age 18. They may involve direct harm, such as physical, emotional, or sexual abuse, or experiences of neglect. ACEs also include situations that undermine a child’s sense of safety and stability, such as witnessing violence, losing a loved one to suicide, or growing up with caregivers who struggle with substance use, mental illness, or incarceration. Many parents don’t realize that even something like a divorce can be very traumatic to a child and can be considered an adverse childhood experience. 

Additionally, chronic hardship—like poverty, food insecurity, homelessness, or unstable housing—can overwhelm a child’s internal stress system and significantly impact development. ACEs are broad because trauma has many forms, and different children experience it in different ways. Yet the common thread is the profound and lasting influence these early experiences can have across the lifespan.

How Common Are ACEs?

ACEs are more widespread than many people recognize. Nearly three out of four high-school students report having experienced at least one ACE, and one out of five report experiencing four or more. Emotional abuse, physical abuse, and living in a household affected by mental-health or substance-use challenges are among the most common. Certain groups—including girls, LGBTQ+ youth, and American Indian or Alaska Native youth—experience higher rates, often due to systemic inequities in their environments.

The Long-Term Effects of ACEs

Exposure to repeated or ongoing adversity can lead to what researchers call toxic stress—a form of chronic stress that alters the developing brain and overwhelms the body’s stress-response system. Children living under toxic stress may struggle with focusing, learning, and emotional regulation. Their immune systems may weaken, making them more vulnerable to health problems over time.

As children grow into adults, the effects of ACEs can surface in many areas. Individuals with high ACE scores are more likely to experience depression, anxiety, chronic health conditions, difficulties in relationships, and economic instability. These impacts are not just personal—they create generational patterns that affect families and communities over time.

ACEs and Substance Use Disorders

One of the most well-established connections in ACEs research is the link between childhood adversity and substance use disorders (SUDs) in adolescence and adulthood. ACEs can increase the likelihood of substance use for several reasons:

1. Coping With Emotional Pain

Children who experience trauma often struggle with feelings of shame, fear, loneliness, or chronic stress. As they grow older, substances can become a way to numb emotional pain or self-regulate when healthier strategies were never modeled or supported. Many adolescents who begin using substances are attempting to cope with unresolved trauma rather than seeking pleasure.

2. Changes in Brain Development

Toxic stress can alter brain pathways involved in reward, impulse control, and emotional regulation. These neurological changes can make individuals more vulnerable to early experimentation, impulsive decision-making, and difficulty stopping once use begins. For some, the brain’s stress circuitry becomes so heightened that substances seem to offer temporary relief—creating a dangerous cycle.

3. Modeling and Access

Children who grow up in homes where substance misuse is present may learn to associate substances with coping or social functioning. They may also have easier access to alcohol or drugs, increasing the likelihood of early exposure.

4. Increased Risk-Taking

ACEs can impact decision-making skills, especially in teenagers whose brains are still developing. Teens who have experienced adversity may struggle with boundaries, self-worth, or identifying safe relationships—making them more susceptible to experimenting with substances or being influenced by peers who use.

5. Statistical Reality

Research consistently shows a strong dose-response relationship: the higher the ACE score, the higher the risk of developing a substance use disorder.
For example:

• Youth with four or more ACEs are significantly more likely to engage in early drinking, daily smoking, and misuse of prescription medications.
• Preventing ACEs could reduce adolescent prescription pain medication misuse by up to 84%.
• In adulthood, preventing ACEs could substantially reduce rates of alcohol-use disorders, opioid misuse, and other addictions.

Substance use disorders don’t occur in isolation—they are often rooted in untreated trauma. Recognizing this connection allows families, clinicians, and communities to approach addiction with greater compassion, insight, and effectiveness.

A Path Toward Prevention and Healing

ACEs are serious, but they are not destiny. Healing is possible at any age, especially when individuals have access to safe relationships and supportive environments. Prevention begins with ensuring that children grow up in spaces that are stable, predictable, and nurturing. This means supporting caregivers, strengthening community resources, increasing access to mental-health treatment, and reducing the burden of poverty and discrimination.

Healthy relationships—whether with parents, extended family, mentors, teachers, or community members—are among the strongest protective factors. Even one consistent, caring adult can buffer the effects of trauma and help a child build resilience.

Preventing ACEs is a community effort. Schools, healthcare providers, policymakers, faith communities, social workers, and neighbors all play a role in creating environments where children feel seen, safe, and supported.

Moving Forward

Understanding ACEs gives us a robust framework for supporting mental health, addressing substance use, and breaking cycles of intergenerational trauma. It also gives us hope. When we create safe, nurturing environments and make healing accessible, we change the trajectory not just of individual lives—but of families and communities for generations.

Children can and do heal when surrounded by compassion, stability, and care. By working together, we can prevent adversity, support recovery from trauma, and help every child realize their potential.
