It's not your job to fix anything.
maybe he has smoked one or two cigarettes here and there.
that does NOT mean he is "smoking"
if it's not a habit, he's not a smoker, just a casual smoker. You can't blame him, he's trying to fit in with friends, still.
you shouldn't have left the note. he probably feels like you hate him and never want him around. your mom is over reacting, i wouldn't give it too much thought -- she'll probably talk it out with him. your dad is probably just feeling horrible right now for what he's done. He was probably keeping it a secret in your best interest, though. you say you don't care to ever talk to him again, but judging by what you've written, it's not true. you seem awfully close to your dad. don't be too hard on him. he's human, he makes mistakes. if you guys didn't want to find out, you probably shouldn't have asked him the question so many times. haha. but really, cut him some slack. it'll make all of you feel better. just don't be so dramatic,
i really really hope things work out for you.
good luck
