ye but u have to understand that some people develop psychosis, schizophrenia, depression etc. and lets be honest when ur baked all u want to do is the stuff u enjoy, so if ur a kid and your going through school your obviously going to learn less cos your too busy enjoyin yourself: skippin school with your buds is obviously more fun than sitting in math class baked off your face daydreaming about random stuff. in otherwards it affects your motivation towards the shitty stuff that u have to do in life . What im tryin to say is for a lot of people in certainn lifestyles its AOK and there's no harm in it but for others, they should just smoke when their lifestyle is less hectic.
