Does smoking cause mental disorders?

The results of two new studies show that psychosis is not only caused by marijuana, but also by smoking.

The studies have been published in the journals Acta Psychiatrica Scandinavica and The British Journal of Psychiatry.

Based on the results, links have been found between psychosis and marijuana and tobacco consumption, especially when it comes to schizophrenia.

Experts say that smoking causes a significant increase in dopamine in the brain and thus enables the development of psychosis, writes Medical News Today.
