That's not true. Your brain keeps growing until late adolescence or early adulthood. One it reaches that point, brain cells quit reproducing. When they die, they're gone for good. They can form new neurological pathways, but not new cells. This is coming from my dad, an anatomy and physiology professor who literally wrote the book.

As for every day life killing brain cells, yeah, I'll agree. I dunno about hundreds of thousands of brain cells dying. Maybe thousands or tens of thousands, maybe hundreds. I'm not really sure. There are several things in life that kill your brain cells. Who's to say cigarettes don't kill brain cells by depriving them of oxygen?

I do take the cannabis smokers' side on the issue. But I do also know from personal experience you can smoke yourself stupid. Smoke at least a quarter a day for a few months, and you will not be as smart as you were a few months ago. You may not notice dramatic IQ changes or anything, but you won't be as smart. Now I am an every day smoker and don't believe I'm getting any dumber by the day. I pace myself now and enjoy smoking just as much. But I believe smoking mass quantities every day for long periods of time will make you dumb. But if you like smoking that much and ain't got nothing better to do, f*#@ it, smoke.
