While the majority of states have a death penalty, methods of execution vary. The Danish company which made the drugs used by most lethal injection method states recently was barred by Danish law from exporting these drugs to countries with a death penalty -including the United States. This has left states scrambling to find new, deadly execution drugs.
Most states with a death penalty include lethal injection as an execution option. Most also allow some other type of method ranging from electrocution to the gas chamber to firing squad.
