Chronic use of marijuana, unlike other drugs, increases neurogenesis in the hippocampus, but this does not lead to the improvement of memory, SCH.CLINIC psychiatrist-narcologist Iveri Kizitsky said with reference to socialbites.ca. to work Scientists from the University of Saskatchewan.
“The study talks about increased neurogenesis in the hippocampus with chronic use of cannabinoids. From here we can conclude that cannabinoids stimulate memory and therefore improve it. However, this does not mean that it is beneficial, because neurogenesis increases, for example, during epileptic seizures. As you know, the harm of a seizure is tens of times greater than its benefit,” he noted.
The narcologist stated that the harmful consequences of the use of marijuana and other drugs are obvious. There is a high risk of psychosis when using marijuana, and between uses the person experiences increased anxiety and depression.
“This is also detrimental to memory; It will be broken anyway. Against this background, even increased neurogenesis in the hippocampus will not help the human condition. The effect of chronic use can be compared to a bone callus: once the bone breaks, it heals and, as a result, becomes thickest at the fracture site. But this does not mean that the bone needs to be broken three times to strengthen it,” Kizitsky explained.
Moreover, as the expert points out, small doses, on the contrary, suppress neurogenesis, which also has a negative effect on the brain.
