Marijuana’s Long Term Effects On The Brain Finally Revealed

The opinions on the effects of marijuana on the brain are divided, and until not long ago, they were a matter of personal beliefs. Scientists are still debating about its long-term effects on the brain and overall health, and it is still illegal in most countries in the world.

On the other hand, alcohol has numerous adverse effects on our health, and it is legal everywhere.

Yet, a recent study conducted at the University of Texas confirmed that marijuana does not lower our IQ, but it can actually enhance the functional and structural connectivity in the brain.

Researchers noticed that the more the participants used this herb, the better and greater the connectivity was.

These findings are really promising, even though the study was done on a pretty small scale.

It also showed that long-term marijuana users have reduced gray matter in the orbitofrontal cortex, even though it was not clear if regular users have a smaller area or marijuana use was the reason for the structural brain changes.

Yet, the Journal of Neuroscience published a follow-up of the study which revealed that there’s no difference between the non-daily or daily use of this herb, which is contradictory to the findings that the regular marijuana use is the cause of the gray matter differences.

Therefore, there is a need for further research, but newest findings confirm the previous claims that cannabinoids may trigger neurogenesis in adults.
