Positive Effects of THC on Older Mice

Cognition and Memory improvement with low dose THC in old mice.

A generally undesired effect of cannabis smoking is a reversible disruption of short‐term memory induced by delta‐9‐tetrahydrocannabinol (THC), the primary psychoactive component of cannabis. However, this paradigm has been recently challenged by a group of scientists who have shown that THC is also able to improve neurological function in old animals when chronically administered at low concentrations. Moreover, recent studies demonstrated that THC paradoxically promotes hippocampal neurogenesis, prevents neurodegenerative processes occurring in animal models of Alzheimer's disease, protects from inflammation‐induced cognitive damage and restores memory and cognitive function in old mice.
