Vicodin may be a household name for those who follow celebrity news, as many of the rich and famous are known for admitting their abuse and Vicodin addiction. One of the most famous to tell their story is Kelly Osbourne, daughter of rocker Ozzy Osbourne.Osbourne wrote in her book, Fierce, the Vicodin addiction started with a simple prescription. Soon her habit escalated from one pill to six pills to 50 pills each day. “Most people would overdose on 10,” she wrote. Her friends and parents quickly noticed her symptoms — drowsiness and nodding off most notably. Eventually she pursued Vicodin addiction rehab, and it wasn’t until her fourth stint that the message of treatment truly sank in.
