I notice in her profile she answers the question "Are you a party girl?" by saying you can bring whatever you like to increase your enjoyment, but she can't supply party treats herself. I read that as: "I do drugs, and you're welcome to use them on the premises, but you'll have to bring your own, as I'm not a dealer."
If that is a correct interpretation of her profile, it probably explains why her responses can be so bizarre: if she's as high as the proverbial kite, she'll probably say anything.
