How do substance use disorders begin?
Substance use disorders develop when the brain’s reward circuitry associates substance use with pleasure or reward, leading to repeated misuse. This is seen as particularly strong in those struggling with opioid misuse. Prolonged opioid use alters the functioning of nerve cells, creating a dependence on the presence of opioids. When opioids are abruptly stopped, withdrawal symptoms occur, which can vary in severity depending on factors like age, usage amount, and duration. These symptoms include restlessness, muscle and bone pain, insomnia, diarrhea, vomiting, and intense drug cravings. These symptoms and rewiring of the brain’s reward system often lead to individuals engaging in high-risk and illicit behaviors that continue to exacerbate their struggles physically, mentally and socially.
Substance use disorders can also be influenced by psychological and environmental factors. Mental health conditions like depression, anxiety, or trauma can contribute to the development of substance use disorders, as individuals may turn to substances as a way to self-medicate or escape from distressing emotions. Environmental factors, such as a family history of substance misuse, dysfunctional family dynamics, or exposure to high-risk social environments, can also increase the likelihood of developing a substance use disorder.
