the first time my dad found my stash he told me i shouldn't be smokeing at the time,so i quit,then about a year later started again,the second time he caught me he just said don't do it in the house(i know he saw the pipe sitting on the desk because he looked right at it) and walked out,only to call my brother afterwards(while he's getting high[my dad smokes btw])and bitches.but now he doesn't care,he told me the other day he smells it all the time and doesn't care as long as i'm not smokeing it all the time during the school year(wich i won't be because if i smoke everyday i become a certified retard)and he's seen me smokeing a joint outside and i didn't really make much effort to hide it(just put it at my side and took hits while he was in the shed )
so maybe your dad won't care as long as your a smart responsible person,but if you do anything stupid or are just plain stupid(not saying you are at all but some people just are blatenly dumb) don't expect him to let you smoke till you smow your responsible(i had to,i used to be an idiot and only smoked weed because it was cutesy,but now i've grown up so my dad treats me acordingly) good luck either way though,i hope your dad doesn't care,it certainly makes things easyer if you have parents that are ok with it
