I'm pretty sure all of my immediate family knows. I mean my step dad helped me move out of my apartment a couple months ago and when he got there he was just like "man....I miss the smell of college" lol. My mom found my stash like three times. The first time she took it all and threw it away. The second time she had my pipe in her hand and I actually grabbed it back and was like "Ok i'll quit but you can't throw my pipe away." It has a lot of sentimental value! haha. Then the next time she found it all and took it and was like "I thought you said you quit" so i had a long sit down conversation with her on why I smoke it and once she realized i was dead set on not quitting and found out I was actually responsible about it she gave me this grocery bag filled with all my goodies. From what my mom told me, My real dad actually got busted slinging so I know he use to smoke. I cant tell if he still does and he never really talks about weed to me so we just keep it on the low-low. My brother has probably seen me do it but he's pretty uptight so we dont talk about it and my sister called me out on it many years ago because she smokes occasionally. plus I look like the typical stoner so that kinda gives it away.
