10. Lethal injections
In case you didn’t know, most states use the three-drug combination for lethal injections; one to stop muscle activity, second to cause the stage similar to coma and the third to stop the heartbeat. Even though it sounds as a simple and most dignified way to die, nobody could really explain the right effect of those injections and if they are painful or not. Even the doses are not finally determined. People who watched the prisoners dying from these injections, testify that these deaths looks highly painful. The reason is the inability of moving due to legs and arms paralyzes while other drugs kill the organs.
