Can Addiction Cause Mental Illness?

 Sean Barlow, M.D., Betty Ford Center’s Chief Psychiatrist, recently responded to the following questions:

  •  What is a ‘working definition’ of insanity? 

Insanity is a legal definition used to base competence, not a psychiatric or mental health definition.

  • Can addiction suppress mental illness?

No.  Addiction tends to make mental illness worse.

  • Can addiction cause mental illness?

Yes.  Addiction can cause substance-induced psychiatric disorders, and the treatment is sobriety – not traditional pharmacological treatment.  Also, there are burgeoning reports that cannabis is a risk factor for the development of psychosis.  If a person is already predisposed because of genetics, environment, social situation, etc., cannabis can hasten the onset of psychotic illness.

  • If a mentally ill person is weaned off addictive substances in a professional fashion, can he/she ever fully regain ‘sanity?’

Yes.  If a patient has lost reason because of drug use, then the person is capable of regaining mental health with proper treatment.

  • Can anger cause mental illness?

No.  Anger is a feeling, although it can be part of mental illness.

    If you have peer-reviewed links to “burgeoning reports” of cannabis increasing likelihood of mental illness, please post them.

    What I find much more likely is that mental illness causes a desire for relief from mental and physical pain, for which cannabis is an excellent therapy, with no competently reported bad effects.

    Once again, peer-reviewed links, please.

    Thank you for the question. The burgeoning reports were not to the causing of mental illness generally but psychosis, and specifically schizophrenia with cannabis use. Here are a number of peer–reviewed articles, and from there many more referenced papers.
