A report in the UK press says:
Obama is sensitive about his cigarette habit and tetchy with reporters who raise it. But after his 90-minute medical at the Navy hospital outside Washington yesterday morning, his doctors confirmed he had not yet managed to conquer the habit and suggested he "continue smoking cessation efforts".
It was described as self-use "nicotine replacement therapy".
News reporters in the U.S. are afraid to write about Obama’s smoking and drinking habits.
