Yes, recovery from substance use can have a positive impact on mental well-being. As the body detoxifies from substances, brain chemistry can normalize, leading to improved mood and cognitive functioning. With substance use no longer clouding judgment and coping mechanisms, individuals can learn healthier ways to manage stress and emotional distress. Recovery programs often involve therapy, which can address underlying mental health issues and provide strategies for long-term mental well-being. Rebuilding relationships and gaining a sense of control over one's life further contribute to improved mental health during recovery.
