well, im 20 so they know they cant tell me what to do anyway but, yeah they dont mind. my dad says he wishes i didnt, my mom is cool with it but likes to pretend shes not! its hilarious. but when i started at the end of age 17, she was cool with it then more than now! most stoner parents like to lie and trick their kids into not doing it, but mine know they did it ALL the time back in the day, so they cant say anything
