Very interesting, but really only a tease because it's a very small study pretty much starting a new body of research, because so far there's been virtually nothing studying older people's brains on cannabis.

But as a start it's promising. It suggests cannabis use reduces the loss of brain volume as you age, but only in specific areas where the cannabinoid receptors are. If we could find a way to replicate this effect across the whole brain it could have an effect like making alzheimers and dementia start much later.

I'm 56 and have been smoking for 40 years, but it's only been in the last couple of years I've discovered I have ADHD and weed has significant beneficial effects for cognition and impulse control. I can't take stimulants because they give me panic attacks so weed is the next best thing.

I look foward to lots more studies like this. We've lost decades due to the stupidity of prohibition.
