David Maraniss’ book, Barack Obama: The Story, describes Obama as a marijuana enthusiast:
“When a joint was making the rounds, he often elbowed his way in, out of turn, shouted ‘Intercepted!’ and took an extra hit.”
Maraniss also describes Obama’s technique of “roof hits” while hot-boxing cars.
“When the pot was gone, they tilted their heads back and sucked in the last bit of smoke from the ceiling.”
Obama has been less than shy about his drug use in the past, writing about the topic himself in Dreams from My Father,
“Pot had helped, and booze; maybe a little blow when you could afford it.”
