When the rules of
baseball were first written in 1845, the carcinogenic potential of chewing tobacco was unknown. At that time, it was commonly used by players and coaches alike. Smokeless tobacco use became rampant by players by the early 1900s. The use of chewing tobacco in baseball steadily increased until the mid-20th century, when cigarettes became popular and took the place of some players' smokeless tobacco habit.
Joe Garagiola, who quit, warned about chewing tobacco:
Bill Tuttle was a Major League player who made a big name for himself both through baseball and his anti-chewing tobacco efforts. Tuttle was an outfielder for the
Detroit Tigers,
Kansas City Athletics, and
Minnesota Twins. He was an avid tobacco chewer; even his
baseball cards pictured him with a bulge in his cheek from the tobacco. Nearly 40 years after he began using smokeless tobacco, Tuttle developed a tumor in his mouth so severe, it protruded through his skin. A few years before he died, Tuttle had many of his teeth, his jawbone, his gums, and his right cheekbone removed. He also had his taste buds removed. Tuttle dedicated the last years of his life to speaking with Major League teams about not using chewing tobacco where television cameras could see the players so that children could not witness and be influenced by it. He also dedicated time to the National Spit Tobacco Education Program, which was being run by friend and former Major League player, Joe Garagiola. Tuttle died on July 27, 1998, after a 5-year battle with cancer. Hall of Fame outfielder
Tony Gwynn died of salivary cancer on June 16, 2014. He claimed the cancer was linked to his lifetime use of chewing and dipping tobacco. A 2016 MLB collective bargaining agreement prohibited all new
Major League Baseball players from using smokeless tobacco. Reporting on the 2016 labor agreement described the restriction as applying to players new to the major leagues, with existing players grandfathered in. Separately, local policies have continued to expand tobacco-free rules at professional sports venues: in October 2025, the Detroit City Council approved an ordinance prohibiting smokeless tobacco (including nicotine pouches) in Detroit professional sports stadiums (including Comerica Park), with refusal to comply subject to a misdemeanor and a $100 fine.
Effect on youth Debate exists over whether players should be banned from using tobacco products during the games. The
Major League Baseball Players Association disagrees, claiming it is a legal substance, so is acceptable to be used during games.
Harvard School of Public Health professor
Gregory Connolly, however, says, "the use of smokeless tobacco by players has a powerful role-model effect on youth, particularly among young males in sport, some of whom remain addicted in future careers as professional athletes." According to Connolly, one-quarter of Minor League players do not support allowing the use of chewing tobacco during games, and one-third of Major League players support abolishing it. A 2009 survey by The U.S. Centers for Disease Control revealed that 8.9% of U.S. high-school students had used smokeless tobacco on at least 1 day during the 30 days before the survey. More recently, the 2024 National Youth Tobacco Survey (NYTS) estimated current smokeless tobacco use at 1.5% among U.S. high school students (0.8% middle school; 1.2% overall). Among U.S. adults, CDC estimates that 2.1% (about 5.2 million) reported current use of smokeless tobacco products in 2021; adult prevalence was highest in the Midwest (3.2%) and South (2.3%). ==Brands==
