Teen Addiction & Adverse Childhood Events (ACEs)

Questions about treatment?

It’s no question that what happens to you as a child can impact the rest of your life. The way your childhood—especially the bad things that happen during it—affects your mental health and the likelihood you’ll abuse substances is complicated, but it’s something people in the mental health industry are trying to understand.

Adverse childhood events (ACEs) is the term researchers and mental health professionals use to describe very stressful or traumatic situations that occur during a person’s formative years.1 Research has shown that ACEs can have a significant impact on the development of substance abuse and alcohol disorders in adolescents.Teenage girl struggling with addiction

Specifically, the more ACEs a teen is exposed to, the more likely it is that they will begin drug use at an earlier age and develop an addiction. One study found that a higher number of ACEs was associated with an increased likelihood of substance use before the age of 14. Additionally, people who experienced 5 or more ACEs were 7 to 10 times more likely to abuse illicit drugs.2

In this article, you will learn:

  • More about ACEs.
  • How they’re linked to teen substance abuse.
  • What treatment is available.

Types of ACEs and How They Affect Teens

Adverse childhood events can be defined as any traumatic, disturbing, or stressful event that causes a disruption in normal childhood development.The events may be either short-term or ongoing, but in either case they must create in the child a sense of powerlessness and the belief that their physical or psychological safety is compromised.4

Although there are numerous types of ACES, some of the more common examples include:3,4,5 

  • Physical, emotional, or sexual abuse.
  • Physical or emotional neglect.
  • Growing up with family members who abuse drugs or alcohol.
  • Criminal behavior in family members.
  • Mental illness in family members.
  • Strife between parents, such as domestic abuse.
  • Parental absence.
  • Traumatic loss of a loved one.
  • Sudden or frequent relocations.
  • School violence.
  • Community violence.
  • Bullying.
  • Serious accidents.
  • Growing up in poverty.
  • Exposure to or participation in pornography.
  • Life-threatening childhood illness or injury.
  • Peer rejection/lack of friends.
  • Parental separation or divorce.
  • Incarceration of a family member.

Although some degree of stress is normal in everyday life, ACEs result in a “strong, frequent, or prolonged activation of the body’s stress response systems in the absence of the buffering protection of a supportive, adult relationship.”5 This means that a child suffering from an ACE believes that they must be constantly on guard or feels as though the world is an unsafe place. They may feel that they cannot rely on their parents or adult caretakers for support and protection; they feel heightened levels of stress and insecurity and feel anxious even in the absence of the ACE.

Some of the emotional, psychological, and mental impacts that ACEs can have on teens include:4,6,7

How It Links to Substance Abuse in Adolescents

Research strongly supports the link between ACEs and teen substance abuse, which is not limited to illicit drugs but includes alcohol abuse and smoking. An important study found that substance abuse “increases proportionally in a strong, graded, dose-response manner that closely parallels the intensity of adverse life experiences during childhood.”8 This means that the more ACEs a teen experiences, the more likely the teen will smoke, abuse drugs, or drink alcohol. The study postulates that a significant portion of addiction development comes from within ourselves and the way we treat each other rather than from the influence of drug dealers or exposure to harmful substances themselves.8

When children are exposed to stressful life experiences, their cognitive and neurological development can be negatively affected, which can impact their ability to effectively cope with unpleasant or difficult emotions. It can also lead to the development of unhealthy and maladaptive coping mechanisms, such as substance abuse.7 In other words, teens who have experienced ACEs may start drinking, smoking, or using drugs as a way to escape from or deal with their day-to-day life stress.

A study of 260 adolescents found that 46.5% had experienced 1 ACE, while 25% experienced 2 or more ACEs. Exposure to a dysfunctional household correlated with a higher prevalence of substance use disorders, while multiple ACEs were associated with earlier and more severe substance use.9

The theory is, these teens started drinking earlier as a way to cope with stress, rather than for pleasure or for social purposes.10

Another clinical review found that people with 4 or more ACEs have an increased risk of smoking (2.2 times), alcoholism (7.4 times), substance abuse (4.2 times), and intravenous illicit substance abuse (11.3 times), as compared to those without exposure to an ACE. These behaviors form what is known as a “trauma organized lifestyle” and are linked with a life-long predisposition to mental and physical health problems.4

Options for Treatment and Recovery

Trauma-informed care (TIC) is a treatment framework designed to shift “the way organizations view and approach trauma.” Its main premise is that the traumatic experiences a person has endured (ACEs, for example) are closely tied to dysfunctional and maladaptive behaviors (such as substance abuse).4

TIC has been adopted by a number of treatment agencies as a way to provide support and care to children and teens who have experienced trauma. Organizations that adopt a TIC approach are able to identify the signs and symptoms of trauma in their clients, acknowledge the impact of trauma, and incorporate “fully integrated knowledge about trauma into policies, procedures, and practices.”4 This is important to avoid re-traumatization (which can occur in traditional treatment settings where people are not aware of the impact of trauma) and to provide effective care to teens who have experienced ACEs.4Teen attending a therapy session

When treating ACEs, clinicians are trained to see each teen as an individual and to look at the unique impact of their specific trauma. Teens who have experienced ACEs require validation and recognition of how traumatic events have affected them; need to learn common coping strategies; and must have access to effective treatments.4 A wide range of therapies are used to treat substance abuse in teens who have experienced trauma, including:

Treatment for adolescent addiction can take place in a variety of settings, including:

The important thing with any of these therapies is that you get into them sooner than later. Early intervention leads to better long-term results, and this is especially important for teens who have experienced ACEs and struggle with substance abuse.
