what form of death penalty does texas use
Capital punishment in Texas Under Texas law, executions are carried out at or after 6 p.m. Huntsville (Central) time "by intravenous injection of a substance or substances in a lethal quantity sufficient to cause death and until such convict is dead".[46] The law does not specify the substance(s) to be used; previously, according to the Texas Department of Criminal Justice the chemicals used for the lethal injection were the commonly-used three-drug combination of (in order) sodium thiopental (a dose which sedates the offender, but not enough to kill outright), pancuronium bromide (a muscle relaxant which collapses the diaphragm and lungs), and potassium chloride (which stops the heartbeat). The offender is usually pronounced dead approximately seven minutes after start of the injection process; the cost for the three substances is $86.08 per offender.[6] As a result of drug shortages, sodium thiopental was replaced by pentobarbital in 2011.[47] Further shortages of this drug have pushed the cost of the drugs to approximately $1300 per offender.[48] Still further shortages of pancuronium bromide (and the expiration of the existing stock) forced the state into switching to a single-drug protocol, using solely pentobarbital.[49]
