Author Kitty Kelley says in her biography The Family: The Real Story of the Bush Dynasty, that the US President first used coke at university in the mid-1960s.

She quotes his former sister-in-law Sharon Bush who claims: "Bush did coke at Camp David when his father was President, and not just once either."

Other acquaintances allege that as a 26-year-old National Guard, Bush "liked to sneak out back for a joint or into the bathroom for a line of cocaine".

Lots of Buzz related to Kitty Kelly's upcoming book on the Bush family. Apparently, a scandalous television news report will be coming out, too.
