Ugh. Anyone who’s smoked crack before will tell you that the ignition point is beneath the rock not above it like a bong and it’s too far away for that to be a functional crack pipe. If it takes her more than two seconds to look at that thing before she figures it out, leave her. She’s obviously no good for you.
If she thinks that its a crack pipe it means she's never been around crack enough to know what one looks like and is a lot less likely to be druggy than someone that knows what a crack pipe looks like
Your sanity will thank you.
