Anna Nicole Smith
The former Playmate and reality TV star died in 2007 from an accidental overdose of the sedative chloral hydrate, which mixed with the prescription drugs already in her body, including four benzodiazepines used as tranquilizers: clonazepam, lorazepam, oxazepam and Valium, also known as diazepam. Benadryl, a diphenhydramine, Topamax, a topirimate and an anti-convulsant, and GABA, also an anti-convulsant, were found as well. (Rob Griffith / Associated Press)
