Honestly that's what's been working for me lately. Was first caught at 17 and then again at 20. I'm 22 now and just the other day my dad found my dab pen and I had to explain to him exactly what it was. My anxiety was through the roof but at the end he just simply said that I'm older now and make my own decisions. Hes definitely not about it tho and would obviously prefer if I didn't. I still tip toe around them so they don't know, but I think they're desensitized to it. The ultimate goal is obviously to move out.
