Marijuana’s Effects on the Brain


I get a lot of questions that have to do with marijuana’s effects on the brain.  So, patients will ask me questions like,

Does marijuana cause abnormalities in the brain?

Does marijuana cause brain damage?

Does marijuana kill brain cells?

Really, I’m going to let the results of one particular study done in 2015 speak for themselves.

In this particular study, the researchers, used MRI (Magnetic Resonance Imaging), to compare the brain size and shape of both marijuana users and non-users.  

These users consisted of both adults, 58 of them, and teenagers, 100, of them.  They used marijuana on a daily basis for at least 2 to 3 months before participating in the study.

The specific parts of the brain that they looked at included the nucleus accumbens, amygdala, hippocampus, and cerebellum.

Guess what?

They found absolutely no differences.  There wasn’t a difference in the shape or the size between the marijuana users and the non-users.
