Long-term use of cannabis or cannabis-based drugs impairs memory, cannabis has implications for recreational users and for treating epilepsy, multiple sclerosis and chronic pain. Mice exposed to cannabis based drug had memory impairments. Regular cannabis use increases the risk of developing mental health problems like psychosis and schizophrenia.
Researchers from Lancaster and Lisbon Universities studied the effects of the cannabinoid drug WIN 55,212-2 in mice and found that long-term exposure impairs learning and memory in the animals. Brain imaging studies showed that the drug impairs function in key brain regions involved in learning and memory. Long-term exposure to the drug impairs the ability of brain regions involved in learning and memory to communicate with each other.
Cannabis-based therapies can be very effective at treating the symptoms of chronic diseases such as epilepsy and multiple sclerosis, and dramatically increase the quality of life for people living with these conditions. Prolonged cannabinoid intake when not used for medical reasons have negative impact in brain function and memory.
It is important to understand that the same medicine may re-establish an equilibrium under certain diseased conditions, such as in epilepsy or MS, but could cause marked imbalances in healthy individuals. Cannabinoid based therapies have beneficial disease-related actions but also negative side effects.
