Substance use disorder is a complex condition influenced by a combination of biological, psychological, and environmental factors. Stress, trauma, and adverse childhood experiences (ACEs) are significant contributors to the risk of developing these disorders.12

Environmental and social stressors, including exposure to trauma, can alter the brain systems responsible for reward, stress regulation, and self-control. When individuals experience chronic stress or adverse events—such as sexual abuse—these experiences can influence the likelihood and extent of substance use. Furthermore, underlying psychiatric conditions often linked to trauma, such as anxiety or depression, may further increase an individual's vulnerability to substance use.12

It is essential to recognize that individuals struggling with the impact of trauma deserve compassionate, evidence-based support. Addressing these underlying psychological and environmental factors is a critical component of recovery, often involving cognitive and behavioral therapies to help individuals develop healthier coping mechanisms and improve their overall well-being.2
