Let her go for it, maybe on an eighth or a little less. Even if she spills her guts after drinking, the fact that she wants to do it again the next day means she's at least tough enough. And really, the worst thing that can happen on shrooms is having a little panic attack get ballooned into a bad trip.


edit: Or walking off a ledge, but it doesn't sound like you'll be shroomin' at the Grand Canyon or nothing.
