Celebrities are no different than other citizens who become addicted to illicit narcotics. If anything, they are more prone to becoming a slave to their illegal cravings because of the proliferation of drugs in Hollywood and entertainment circles, because of their thicker wallets that enable them procure the substances, and because of flunky hangers-on who do little to stop them — or even help the stars obtain them.
Many have never come back from their descent into addiction (read: Elvis, Janis Joplin, John Belushi, etc) or, as comedian Katt Williams and actresses Lindsay Lohan and Amanda Bynes illustrate, they are in the throes of their addictions and their bizarre and frightening behavior as it plays out before the world.
We can only hope that Williams and Lohan turn out like the following celebrity drug addicts who have recovered and went on to have great careers.
