asvjerry,
Cocaine "derivatives" (not quite, but its cousins so to say) are usually used for "not-mind-altering-anesthesia". Think local, topical, spinal, etc. PCP cousin (ketamine) could make you talk gibberish while not really being there. Not that I have an answer, or that it matters, but just like that heart attack and pacemaker. Apples in the apple bag, oranges to orange bag. Well, maybe you can ask what it was so, in case you need it next time, you can pick and choose.
