Drugs - a theme

Of the many themes touched upon by Bob Dylan in his Theme Time Radio Hour, he spent time on three specific, socially-acceptable chemical dependencies – whiskey, coffee, and cigarettes. But he didn't touch on the underbelly, the illicit side of things.  Why do songwriters touch on such things?  My smart-ass answer is "because they can."  But seriously folks, these kinds of things are more available to them once they become "successful."  Musicians, for better or worse, are seen as people who have made it financially and live the high life [no pun intended].  Unsavory characters who want to get close to musicians use drugs as a tool to get themselves closer to the high life they want for themselves.  Some musicians are depressed, some have suicidal thoughts, some have some kind of chemical imbalance, and some are just bored with their own existence.  Stories about addiction and drug abuse have been part of our culture in music, books, and theater for centuries. As long as people are in some sort of pain and there’s something to let people get away from that pain, drugs will be a topic for "the arts."

The rules – 1) only one song/artist [because some have quite a few drug songs]; 2) the song is in my collection.
