My father has been smoking pot since he was 13 years old, he turned 45 years old last month. that means he has been smoking for 32 years straight (as a kid i would always find his stashes). He only has a grade 10 education, (like alot of people from that time) but he is one of the smartest people i know. He has worked in managment for 27 years making over 50k a year. He owns 277 acres of georgous property and a very nice house. SO there is a case that goes against pot making you stupid if you smoke it at a young age. Also my father is 6 feet 3 inches and i can tell you that he wasnt that tall when he started to smoke.
