Ketamine is also known as: 2-(2-Chlorophenyl)-2-(methylamino)-cyclohexanone hydrochloride, Vitamin K and Special K.

Chemically, it is related to PCP but produces more profound acid-like experiences in low doses. Frequently produces bad trips, psychotic reactions and extreme violence in its users (kinda like Windows :-)).

For those do-it-yourselfers out there, the chemical formula is:

C13H17C12NO
