hey tourist. just explain to her in a logical well thought out manner exaclty what your intentions are. you obviously have medical needs, and she would like to try it. explain to her that you'd only have a couple of plants, that neither of you will ever tell anyone, what the initial investment would be, how people get caught and what you are gonna do not to (not that this is a concern, but i think it would help alleviate some of her concerns), and if she doesn't want to or is hesitant then ask her to let you just start a couple of plants out and get things going so she can see how it works and what's going on and understand it. let her know that if she feels uncomfortable with it at any time you will abort it all together. more than likely if you are reasonable with her she will be with you (hopefully). everyone wins. now blaze that sh*t!
