title: Report on smoking habits of Winnipeg school children: 1960-1968.
abstract: A third survey of the smoking habits of all the students in the Winnipeg School Division from grades 5 to 12 has been completed. The three surveys cover a period of eight years and show an increase in smoking at all grade levels in both sexes. The increase is most marked in the girls and in both sexes it is most marked at the elementary school level, indicating an earlier onset of the habit of smoking. These studies indicate that present efforts to reduce the smoking habit are ineffective at the school level.
