Two anti-smoking groups announced plans to “monitor the smoking habits of professional baseball players and how the 12 professional teams are supervising their underage players.”

The Japan Society for Tobacco Control and Japan Medical-Dental Association for Tobacco Control will submit questionnaires to all 12 Japanese professional pro baseball teams in an attempt to find out about the smoking habits of players.

The survey comes on the heels of a media uproar over revelations that 18-year-old Japanese-Iranian Yu Darvish, the top draft pick for the Hokkaido Nippon Ham Fighters, was caught smoking during spring training a short while ago.
