Cannabis decreases dopamine synthesis in the brain

London - The "amotivation syndrome" observed in chronic cannabis users could have its cause in a reduced dopamine production in the brain, report British brain researchers in Biological Psychiatry (2013; doi: 10.1016 / j.biopsych.2013.05.027).

Michael Bloomfield of Imperial College London had actually expected a different result. The brain researcher used positron emission tomography (PET) to examine the dopamine concentration in the brain of 19 chronic cannabis users. All suffered from psychotic symptoms. Delusions or other positive symptoms of schizophrenia developed while using cannabis.

Bloomfield had suspected that this was the result of increased dopamine production in the reward centers of the brain. Instead, the PET images showed a significantly reduced dopamine concentration. Although this cannot explain the psychotic symptoms of cannabis users, writes Bloomfeld, it could, however, be the cause of the "amotivation syndrome" which is very often observed in this group.

Cannabis users are often listless, passive, and lackluster. The indifference to everyday demands often leads to academic and professional failures. © rme / aerzteblatt.de
