you know what i'd do? (considering i won't take authority from anyone...i wouldn't even take it from police but yea they can call a bunch of cops and hog tie me so resisting is useless) i'd tell her that if she wants you to quit she has to leave her bf or make him stop as well...double standarding is a bitch...and tell her if he refuses to quit then so do you. imo you can't tell someone not to do something unless they themselves are clean from the involvment of the said act...that includes dating someone that does it as well....tell her he sets a bad example for you....and if all else fails i'd roll the fatest ass sweet i could, walk up to her smoking it and blow the smoke in her face....as a sign of you're not going to quit...but that's just me and unless you got the balls to do it full throtle and ready to face consequnces i wouldn't reccomend it for you. my grandma screwed up with me a loooooooong time ago...when i was bout 7 she told me "no one can make you do anything you don't want to do" and i realized that...no one can physically make you do anything....sure if you resist the cops can take you to jail and use extreme force to get you there...but they can't make you comply...
