A new book from Pulitzer Prize-winning author David Maraniss "Barack Obama:The Story" is a boom for anybody in the US.

The book tells the story of young Barack Obama, when he was smoking pot back in 1970s.

The president and the group of his friends at the Punahou School at Honolulu were playing baseball, smoking dope and  calling themselves "Choom Gang".

According to the author, Obama was known for starting a few pot-smoking trends. One of them was called the "TA" short for "Total Absorption", which was basically a penalty to any member of the Choom Gang who didn't fully inhale the joint. All the members who dared to exhale before the full absorption "were assessed the penalty" and were skipped the next time the joint come around.

Just to remind to everybody - Barack Obama's campaign slogan was "Yes We Can" - and now he is hoping to be reelected in November - will see where this book will take him!
