What is the relationship between drug abuse and mental illness?

Cheers and hurray.

Thank you for giving me the answer.

The relationship between drug abuse and mental illness is complex and bidirectional. Individuals with mental health disorders, such as depression or anxiety, often use drugs as a form of self-medication to alleviate their symptoms. Conversely, drug abuse can exacerbate or trigger mental health issues, creating a vicious cycle of addiction and worsening mental health. Research indicates that co-occurring disorders are common, with individuals experiencing both conditions facing greater challenges and poorer outcomes. Addressing both drug abuse and mental health issues concurrently is essential for effective treatment and recovery.
