I find the arts can help you stave off potential urges and help to resist the long-term cravings that pop up (seeing advertisements, other people doing them) and focus your attentions on it. By focusing on it, you're no longer worried about drugs. You lose yourself in your environment of self-expression and it helps to free you from the restraints of life. I like to draw. Architectural buildings. Roses. People's expressions. Whatever the case may be, what do YOU do?
