Not all rock stars embrace sex, drugs, and rock and roll. Here are five rock stars that largely avoided the excesses of stardom. Frank Zappa never touched alcohol, cannabis, or any other drug for that matter. Instead, he was focused on the business of making music. Henry Rollins stated, I tried marijuana and LSD. It was interesting, but nothing I wanted to make a career out of. Bruce Dickinson suggested that his attitude in controlling his arrogance on and off stage is the reason he didn't become one of those rock stars who became a victim of drug addiction. Roger Daltry made a vow to stay away from cocaine and even avoided marijuana due to his intolerance to smoke. Bruce Springsteen, despite his struggles with depression and exhaustion, has maintained a drug-free lifestyle.
