Local and global anesthesia use it often, actually even though you'd think it's the anesthesiologist that uses it (because they are known to be drug fiends) usually it's the surgeon who makes use of cocaine. I remember in my medical training that old surgeon Dr. Jackson, he'd have that thick moustache that'd always look like it'd been dragged through flour. But then he'd say "let me show you how to do surgery young paduans" and I'll be damned if he didn't perform 18 whipples, 13 trepinations, and 32 colonostomies in an hard-drivin' 48 hour continuous surgery jamboree
