You have a BIG thing in your favor - if she smokes, she already knows that most of those myths about cannabis are just that, myths.

So, you won't have to sell her on the fact that it isn't as dangerous as it's made out to be.

1. You didn't want to buy from dealers; you felt it was safer for you this way.

2. You will give her as much as she wants from your plant if she would like to have it.

3. You will let her supervise your smoking habits if she agrees to let you continue smoking responsibly.

4. You are NOT selling it. And if you are selling it, you might want to stop or at least tone it down to your closest friends.

Good luck, just be truthful and try to be mature about it. Apologize for hiding it from her but tell her you did it because you were concerned for your own safety, being a kid and buying from dealers isn't that safe, and any parent will realize that.
