you need to tell your parents to stop bugging you, your smokin weed so you have obviosly developed your own ideas of right and wrong, dont let them try forcing there ideas of right and wrong onto you, i dont mean this in a nasty way cause my parents were quite strict on it too, so i told them that its better than alcohol and les destructive, they didnt agree so i shouted 'ha i did coke on new years eve' and generally went mad
