I just think the phrase 'killing brain cells' is one of the most vague statements, and should never ever be used.

Over the past five years since I've been drinking, I've probably blacked out like 100 times at least lol. And I won't even be legal age until this summer lol.

Add to that, I've drank 20 plus beers while rolling a few times. I've drank very heavily while smelling white things on countless occasions. I've smoked enormous amounts of marijuana while drinking and while not.

Just saying, not that I disagree with anyone here....but from my personal experience, substance use has done no harm to my brain, body, or organs as far as I'm concerned. I still have the most unbelievable long term memory that even people who are sober say 'Wow'. Still got an above average intelligence. Still in great shape. 'Oh Mac, the damage will come soon enough'. Yeah, I doubt it.
