Can drugs cause mental illness?
It is well-established that substance abuse and addiction can contribute to the development of mental health disorders. Research suggests that drug use can lead to changes in some of the same areas of the brain that are affected by mental illnesses, such as mood disorders, anxiety disorders, impulse-control disorders, and schizophrenia.
Additionally, people who struggle with addiction may experience other negative consequences that can further contribute to the development of mental health disorders. These can include social isolation, financial difficulties, relationship problems, and legal issues, among others.
In cases where a mental health condition occurs simultaneously as substance abuse disorder (addiction), most addiction treatment programs will issue a dual-diagnosis diagnosis. This way, the mental health issue can be treated alongside the addiction to help shut down any correlations that may be exacerbating both issues.
