Superstar Michael Jackson died in 2009 from an overdose of propofol, a medication used to put people under during surgical procedures.
The Missouri Supreme Court recently ruled that the state can use propofol to execute inmates on death row, even though the U.S. maker of the drug, Fresenius Kabi, prohibits the drug for use in executions.
"This is an experiment with a human subject. This will be sort of a brute force approach where you give them enough and they die," Richard Dieter, executive director of the Death Penalty Information Center, told the Associated Press.
Propofol is usually given by a physician, but Missouri doesn't require a physician to be present during an execution, which could mean trouble.
"From my own point of view a firing squad is a lot safer, a lot quicker, and a lot less painful," added Dr. Jonathan Groner, a professor of clinical surgery at the Ohio State University College of Medicine.
Missouri Attorney General Chris Koster said in a statement that the court "has taken an important step to see that justice is finally done for the victims and their families."
Koster did not address the problems connected with propofol.
