What were some slang names for cocaine in the 1920s?

cocaine is a drug used recreationally by people but it is commonly thought to be a Schedule I narcotic in the US. This is wrong. Cocaine HCL is actually a Schedule II substance and can be dispensed with a prescription. Another form of Cocaine is Crack. Crack Cocaine is basically Cocaine that has had all the impurities cooked out of it and it is smoked in a little stem with chore boy giving the user an instant "tweeky" like "Superman" like feeling. It's a little weird and can't describe it. The way that drug tests test for cocaine is by locating ecgonine in the urine or blood stream. Ecgonine is a metabolite of cocaine.
