The Link Between Trauma and Addiction
Trauma disrupts the brain’s natural coping mechanisms, leaving individuals overwhelmed by emotions such as fear, sadness, or anger. When trauma is not addressed, it can lead to chronic stress, anxiety, and depression.
In an attempt to numb these painful feelings, many turn to substances or behaviours—such as drugs, alcohol, gambling, or overeating—as a form of self-medication.



Research has shown that individuals with a history of trauma are significantly more likely to develop substance use disorders. This is particularly true for those who have experienced Adverse Childhood Experiences (ACEs), which include physical, emotional, or sexual abuse, neglect, and household dysfunction. ACEs can disrupt brain development, increase sensitivity to stress, and weaken the ability to regulate emotions—all of which heighten vulnerability to addiction. Substances or addictive behaviours may offer temporary relief, but over time, they can exacerbate feelings of isolation, guilt, and shame. Addiction, in turn, often reinforces the unresolved trauma, creating a cycle that feels impossible to escape.
