Question

Quizplus · Accepted Answer

The impure residue left after boiling away a solution of cocaine hydrochloride and baking soda is commonly known as crack. This is because the process of boiling the mixture with baking soda results in the formation of solid, crystalline structures that when heated produce a crackling sound. Smack refers to heroin, which is an entirely separate substance unrelated to this particular process. Lidocaine and procaine are both local anesthetics that may be used in combination with cocaine, but they are not the residue left after a drug preparation process.
