The investigation into Michael Jackson's death is zeroing in on what drugs the pop singer may have used and who provided them to him.

A toxicology report, due out within the next few weeks, will answer some of the questions that remain about the entertainer's death. Some say an incident in which Jackson received third-degree burns may have led to an addiction of pain killers.

After that time, Jackson admitted to being addicted to heavy pain medication and to seeking help in rehab.

Jackson's death is calling to attention steps health care professionals say still need to be taken to combat prescription drug abuse. Federal authorities are considering making the anesthetic Propofol, which is one of the drugs found Jackson's home, a controlled substance.

Local doctors and treatment specialists say there is still much more that needs to be taken to combat the issue of prescription drug abuse.

Years before Jennie Amison became executive director of Harrisonburg's Gemeinschaft home, she needed drug counseling herself.

"I could recall even stealing my girlfriend's mother's prescription drugs because we got high off of prescription medication, Percocets," says Amison.

She says she used to abuse a wide variety of drugs. She says it came from a combination of being abused as a child and peer pressure.

One day in 1986, she was in the hospital visiting her father when he was dying. She describes some of her actions to feed her addiction at the time.

"I didn't have the needle to use, so they would put them in their little box. And I would get one of those needles to shoot my drugs. That's the desperation. That's how far addiction will carry you," says Amison.

Dr. John Sherry knows about addiction. He's a specialist at Blue Ridge Pain Treatment Center in Harrisonburg.

"You have to be very paternalistic and treat your patients in such a manner as to say no," says Sherry.

Sherry screens his patients every three to four visits. He says not all doctors will do that.

"I think it's suicidal for that type of practice to not have that. The federal government is scrutinizing these things. And when they come across a pain center that does not do that, there are major issues, because it's like you're not doing your job to make sure your patients are safe," says Sherry.

In 2005, the U.S. Congress passed a bill Sherry supported that aimed to create a national electronic data bank for monitoring the use of many controlled substances.

However, Sherry says the program remains under-funded to this day and the issue of prescription drug abuse is worsening.

"I have to be really careful today. I have 18 years [of sobriety], and I still have to be careful," says Amison.

In West Virginia, this has become a particularly significant issue. A recent media investigation found drug overdose is now the state's leading cause of death among adults under 45.

West Virginia's Health Statistics Center reports more people in the state die of drug overdoses and other poisonings than in traffic crashes.
