If you think dope is for kicks and for thrills, you're out of your mind. There are more kicks to be had in a good case of paralytic polio or by living in an iron lung. If you think you need stuff to play music or sing, you're crazy. It can fix you so you can't play nothing or sing nothing.
In this country, don't forget, a habit is no damn private hell. There's no solitary confinement outside of jail. A habit is hell for those you love. And in this country it's the worst kind of hell for those who love you.
I can't stand to sing the same song the same way two nights in succession, let alone two years or ten years. If you can, then it ain't music, it's close-order drill or exercise or yodeling or something, not music.
