I agree with hug, it might be best if you did let her do it. You can set the place time, etc. so hopefully she does have a life changing experience for the better. It may even be your responsibility to do so. She seems very intrigued, and I can only imagine the hell that might unfold if one were to take a large, or far too large, of a dose in the setting of a party.
I recommend trusting the molecule. Either she will have a powerful, moving event, or she will have the daylights scared out of her in a way she never thought possible, and likely swear the whole thing off. In either case, at least she would have a level headed person, and someone who actually cares about her like you there for support. At least with you being the one, she can be educated in how to approach the thing with respect, and the proper mindset. It just seems to me that it will be inevitable that she gets it, going off of how you described her.
I know it's a lot to bear if you do offer it. I have some friends that are very interested in mushrooms, and it twists me up into a knot. I know how good it can be, but I also know how bad it can be. I am the one with knowledge of what I am giving to them, I know it's true nature, they have no idea, and that's a very heavy thing. It's a decision not to be taken lightly.
