Pardon me, but this makes nearly no sense

Alert on Doctors’ Abuse of Propofol, Drug Suspected in Michael Jackson’s Death – WSJ.com
Abuse of the sedative suspected in Michael Jackson’s death is a growing problem among medical professionals, increasing pressure on the government to restrict it as a controlled substance.

So, doctors (a very very few) abuse this drug, so the answer is to…restrict its prescribing to doctors.

Brilliant!
