I smoked nearly everyday from about 15-24. In fact, there was a point where I simply assumed I would smoke everyday for the rest of my life.

At age 25 I joined the military. Haven't smoked in almost 15 years. That said, I still feel like I really damaged my memory and it has never quite recovered. It would be very interesting to study the memory of individuals like me who smoked habitually during their teenage years and then stopped completely.

Theres definitely research out there. I'm tired and eating breakfast atm but I recall seeing things that smoking a lot before your brain is done developing (22-25) is significant. Even if you stop.

My memory is absolutely fucked from smoking weed for a few years on and off.
