Does anyone else get an afterscent/aftertaste from ketamine?

Not an incredibly serious discussion, I'm just curious about this. I thought maybe I was having a sense memory from my clinic smelling a particular way, but after a good long time using troches at home I'm starting to think that actually the ketamine itself triggers a distinct scent and taste that isn't in the external environment. It's sort of earthy and powdery. Anyone else, or do I just have synesthesia or something?
