thanks for all the help you guys. basically i hid my plants and paraphenilia (if thats spelled right) and told her if she told, i would tell my parents that she is sneaking her bf into th ehouse at night. and i talked to my mom who is i guess not a hypocrite. she said "i cant stop you from doing what you wanna do. if your gonna smoke weed and cigarettes, dont do i tin the house. i know weed is harmless, just dont get your dumbass aressted. and i will takl to your father." so my sister did end up telling, but my mom already knew and she basically told her to grow up and quit being a fucking tattletale. thanks for the help. at least now i cna do what i want worry free
