i'm sixteen and i have been smoking sinse i was 12, at least once a week for three years. my brain has been developing throug all of that time. i go to the second best state school in the country (i'm not boasting but it prooves a point) not only do i not think that weed has inhibited my brains development i believe it has played an important role in devbeloping my personality, i am now an easy going generous person, i don't like fighting and i like talking not shouting, i don't mug old women. also last point i'm sure you trust your weed to be weed and just weed, if you refuse to sell a minor good clean weed you are increasing the chances of him going to someone who will put crak in their "weed" and yes i have smoked what i thought was weed and was clearly not just that in that exact circummstance. i do see your points i think you just need a different perspective to make a decition on ethical isues. xx
