If they were growing I'd send those plants down the garbage disposal. If they were smoking and they were a teenager I wouldn't ground them if I found out or anything but I wouldn't let them do it in my house, if I was there. Because I wouldn't wanna be charged with contributing to the deliquency of a minor. Why wouldn't I let them grow? Well I'm in highschool right now (16) and everyone I know who grows is selling, and I wouldn't want it in my house. No one I know "grows recreationally".
