After the recent death of Michael Jackson, and possibly Brittany Murphy, due to prescription drug overdoses, Steven Tyler, the lead singer of the mega-band Aerosmith, has checked himself into rehab for pain-killer addiction.
Many pain killers commonly used are opiates (which are very similar to heroin), and many chronic-pain sufferers resolve to taking such drugs in high quantities and for many years. Such use can easily lead to dependence and serious withdrawal symptoms.
We wish Tyler all the best in his rehabilitation efforts. Stay strong Steven!
