the longer you can wait before you smoke again gods honest it will be better, i started at 14 wish i didnt i cant really remember much of those days, every year you wait the less risks you are taking with your mind and you can get to know who you are alot better when you get older, also id say the younger you get into it the more likely youll go for harder drugs as u get older as happened 2 alot of people i kno
but its up to u really, and its hard having 2 choose since u must of been attracted to it because of your parents.
oh yeh the key point i forgot to mention is how much you smoke, i used 2 smoke everyday at 14 but if you kept it to weekends then u are sorted mate
