Cannabis shrinks brain,BUT increases connectivity
The scans revealed that smoking cannabis every day was associated with shrinkage in the orbitofrontal cortex region of the brain, which is involved in mental processing and decision making.

It also influences responses to rewards and adversity, and is strongly linked to empathy - the ability to sense other people's feelings.

Neuroscientists believe damage to the orbitofrontal cortex may underpin some forms of psychopathy.

Earlier onset of cannabis use induced greater structural and functional connectivity, the research showed. The greatest connectivity increases occurred as an individual started taking the drug.

After six to eight years of continually taking cannabis the increases in structural wiring declined, but users continued to display higher connectivity than non-users.

Regular cannabis use shrinks the brain but increases the complexity of its wiring, a study has found.

To some extent the loss of brain volume is balanced by larger numbers of connections between neurons, scientists discovered.

So how much shrinkage after (hmm, lemme see, carry the 2) 40 years of smoking OP? I don't think this shows statistical significance.

Interesting anyway, thanks.

The human body is amazing in how it can adapt and try to compensate for all the garbage we put into it...the heart can build its own bypass system if the blockage is slow over time and not sudden...there's thousands if not millions of ways the body adapts to our abuse.

So really, smoking pot just makes your brain more efficient. Cool! I might have to try it someday.
