I can remember the convo with my mother when I told her I get high. I explained that I'd been doing it for years and pointed out some memorable moments from our past where I was stoned and she would be sure to remember the times I was talking about to show her it's not the demon weed they say it is. It's still illegal where we were at the time, if you're a legal MMJ patient wtf are they going to say? Explain why you use it, it's as simple as that. What are they going to disown you? Seriously if you have to worry about that you've got bigger problems than them knowing you smoke weed.
