In a paper published in the October 25 issue of the medical Journal of Neuroscience, researchers at the University of Bristol, in the UK, say that cannabis has been demonstrated to cause adverse side-effects on concentration and memory in humans.

After the plant is used, brain activity in areas where these traits are controlled becomes inaccurate and uncoordinated. This is one of the main mechanisms that lead to the altered states of mind that characterize cannabis use.

The investigation was led by UB School of Physiology and Pharmacology expert Dr. Matt Jones. He was the one who came up with the idea that researchers should test for a link between cannabis use and “disorchestrated” brain networks.

“Marijuana abuse is common among sufferers of schizophrenia and recent studies have shown that the psychoactive ingredient of marijuana can induce some symptoms of schizophrenia in healthy volunteers,” Dr. Jones explains.
