I live with a parent, and they were home when it arrived. They aren't chemists, or scientists so just from reading "Sodium Nitrite" on a bottle they wouldn't be able to tell what it was. I have some acne problems and sometimes like to try new products to help my skin heal faster and stuff like that, so when it came I lied and said it's just some powder I ordered online that's supposed to help my skin heal faster that I can use as a mask. I even said that I wanna try it later so I didn't wanna open it yet so I didn't even have to open and show them the bottle outside of the plastic bag. I don't know if they fully believed me or what exactly they thought it might've been but whatever they thought they haven't asked me anything about it ever since and never even mentioned it again.
