This drug is a barbiturate that induces general anesthesia when administered intravenously. It can reach effective clinical concentrations in the brain within 30 seconds, according to an Amnesty International report. For surgical operations, patients are given a dose of 100 to 150 milligrams over a period of 10 to 15 seconds. This in itself is a lethal dose. It's believed by some that after this anesthetic is delivered, the inmate doesn't feel anything.
