Tom Petty died of an accidental drug overdose.
Misuse of prescription opioids.
Tried to find the original thread, but failed. Just read a story about it in the 3 days of papers that got delivered today because of the snow.
Unfortunately, more people are dying in the USA of opioid abuse than from breast cancer. It is one of the leading causes of death for young people.
