At the same time, I would be willing to bet that labeled musicians are even less likely to use drugs/alcohol than indie artists. When supply is so high and demand is so low, labels don’t need to waste time taking chances on substance abusers. Tour schedules are so tight that most artists now do everything they can to prevent illness or other damage to their bodies.

The idea that a rock-star is drunk and/or high 18 hours a day (or even a smoker) is an outdated stereotype. There is no longer enough room for error to allow that kind of behavior across the board.
