What Are Some Songs That Are About Drug Addiction That Have Intense Lyrics?

I’m doing an english essay and i have to have three sets of lyrics about drug addiction that i can write about. It would be great if there were some from different points of view, like some one who wants to stop, a mother or friend watching whats happening or some one who likes the thrills and thinks it’s a good thing etc….Thanks if you can help me out 🙂
