Don't ask me, I'm not a chemist but according to one:
Ketamine hydrochloride ("Special K" or "K") was originally created for use as a human anaesthetic, and is still used as a general anaesthetic for children, persons of poor health, and in veterinary medicine.
Ketamine belongs to a class of drugs called "dissociative anaesthetics," which separate perception from sensation. Other drugs in this category include PCP, DXM and nitrous oxide (laughing gas).
Ketamine usually comes as a liquid in small pharmaceutical bottles, and is most often cooked into a white powder for snorting.
The only thing that separates these drugs from one another is an oxygen molecule or two. Does that mean that they guy shooting up China White isn't a heroin addict because, technically, it's not HEROIN?
Sound like you guys are on your way to becoming greenbeans to me.
