i wouldn't quit unless you really want too,to be honest it sounds like you have good parents,and it's good your so respectfull and understanding of them,you acctualy sound alot like me,and trust me your parents wont ever understand but luckily my dad smokes too,just doesn't want me smokeing as young as i am(well was,now he doesn't care and hasn't for the past six months but before he didn't want me doing it)my dad found my stash box and just talked to me about it for about 20 minutes no yelling just "get your stuff together,and when your older and more responcible you can smoke all the weed you want"and to be honest at that age(which was 14 i'm 16 in twenty days) in retrospect i agree with him and i'm glad he did stop it from getting to bad,but now he knows i'm not putting myself in the situation to get myself arrested or in any kind of trouble to do with anything,i'm all for avoiding conflict but i still cover up the smell and all,i think it would be a little disrespectfull to him for his house to reek of weed when he comes home but if he just smells a little wiff walking past my room he doesn't care.good luck with them and i hope they are a little more tolerable while still keeping everything in control
