Thats awesome. The thing with parents is to keep denying their accusations (unless they catch you in the act ofcourse). I always come home krunk and when my mom thinks im on something i just simply say "no". What most people need to find out is that in most cases their parents love them and dont want them smoking weed and dont want to know they are doing it, so if there is any doubt that you did something you shouldnt have, they will believe you when you keep saying "no".

keep on blazin bro
