Not that it changes much of the thinking on the subject, but PNP likely includes more chem sex drugs than meth. It could include G or K (I forget what "G" stands for, K is ketamine, a horse tranquilizer. Also, the provider may be open to clients using but not use themselves, or may use a different chem than the client. If the whole area is something you want to avoid, either avoid those who list PNP or be clear about your expectations and what you won't tolerate.
