I need advice

I’m 19 and have been taking 7 oh daily since last march, today I got a package from one of my venders today but when I got home it was gone, my mom opened it and said that we’re gonna have a talk about how dangerous it is, I highly doubt I’m getting that pack back, but how do I explain to her that this stuff isn’t dangerous, literally the one of the first things that pops up when you google 7 oh is misinformation that you can od or it causes respiratory depression which is entirely not true, but I don’t know what to do tbh, I’m probably going to be forced to quit but the withdrawal are genuinely the worst thing I’ve experienced in my entire life, but besides the withdrawal 7 oh has improved every aspect of my life, and I’m just not ready to quit. What do I tell her
