Good question indeed. It seems like there are so many addictions off of legal pain killers. I think the answer is not making them illegal but get better regulation.
This is an interesting question. Prescription drugs can be just as dangerous as illegal drugs, but they can be obtained legally. This doesn't mean that prescription drug abuse is legal, though--using them for purposes other than what they were prescribed for is actually illegal. Prescription drugs are therapeutic when used correctly, so making them completely illegal would keep people with legitimate medical problems from having access. I agree with armyofone, that good regulation is the key. Regulation is supposed to keep prescription drugs legal for legitimate purposes but make them illegal for other purposes.
According to the U.S. Office of National Drug Control Policy, "Abuse of prescription drugs to get high has become increasingly prevalent among teens and young adults. Past year abuse of prescription pain killers now ranks second—only behind marijuana—as the Nation's most prevalent illegal drug problem."
