Dr. Murray -- You Give Propofol A Bad Name

There's a new drug problem in the U.S. -- Propofol.

We've called a bunch of hospitals and anesthesiologists who tell us ... since Michael Jackson's death a number of patients were worried sick about being put under with Propofol. The docs have had to walk their patients through the procedures they use to ensure safety.

We're told some patients are outright refusing to be put under with the drug that killed M.J.

The medical experts we've spoken with say Propofol is a great drug that is relatively safe when administered properly -- that was clearly not the case with Jackson.
