Procaine, a numbing agent related to novacaine and cocaine, used as cocaine, but much cheaper, and legal to purchase. The procaine is cooked like as if you were using cocaine to cook crack, the end result is identical to crack in look and feel and smell, but when melted and injected because procaine and not cocaine was the end user can risk, and about 75% of the time does, having a heart attack because of the ingedients in procaine. This is where the term chest busters is used.
