Trust me. I seen kids in my shit highschool who could learn high better than drunk. I've had my fair share of getting drunk during school and has effected my learning for those days and maybe the day after if I got wasted, but I've smoked almost every single day during grade 8 to 12 and never has it affected me like Alcohol.

I don't trust the first link
The second didn't quite take into account eating habits and lifestyle which could also attribute to stroke and the other said they couldn't separate the tobacco smokers from the weed smokers because they all has nicotine in the system
The third needs more research
And the fourth is just the old mind power loss which is true, but wrong at the same time.
It's about the time when you start smoking. It's not like once, you're gunna go dumb. If you start at the age of twelve with absolutely no brain training like not paying attention in school or picking up a hobby then of course your thoughts are going to rot, but that being said. If you're already a full grown adult and had never or barely smoked before then this is ruled out, pretty much.


How many do you think are born in a fucked up life with a fucked up brain most likely and turn out to be complete ass holes in a the future? I know the world needs to keep spinning, but it's so unnecessary that this happens.
