Are We Through With Chew Yet?
There has been some progress. The organizer of America’s fastest growing sport, National Association for Stock Car Auto Racing (NASCAR) has dropped its long-time affiliation with Winston tobacco. NASCAR president Mike Helton says a total tobacco ban is “an issue that’s on our radar for next year.”
And there have been setbacks in the fight against smoking tobacco. New marketing campaigns that feature flavored smokeless products have won over new young users. Journalistic coverage of Dr. Brad Rodu and his support of smokeless tobacco as a substitute for cigarettes has diluted the Academy’s “No Smokeless Tobacco Use” message that has been an official campaign for this Academy since 1989. In a November 10, 2005 study; “New Cigarette Brands with Flavors That Appeal to Youth: Tobacco Marketing Strategies; Health Affairs, November/December 2005, Volume 24, number 6, funded by the American Legacy Foundation and the National Cancer Institute noted that candy flavors were also added to smokeless tobacco products, cigars and cigarette rolling papers. “
Kicking Tobacco Means Kicking It All
The results “clearly showed that the levels of cancer-causing nitrosamines are far higher in smokeless tobacco products than they are in medicinal nicotine products,” Hecht said during a press briefing. While smokeless tobacco has “demonstrably less carcinogens and toxins than cigarette smoke,” said Hecht, smokeless tobacco still has “remarkably high levels of carcinogenic tobacco-specific nitrosamines -- levels that are 100 to 1,000 times higher than in any other consumer product that is designed for oral consumption.” In a separate study, the team evaluated carcinogen biomarker levels in individuals using these products. They had 54 users of popular US smokeless tobacco products use their usual brand for two weeks and then had them switch to either Swedish snus or a nicotine patch for four weeks.
The team found that carcinogen levels in urine were statistically significantly lower after the switch from US-made smokeless tobacco brands to snus or to the nicotine patch. When comparing snus users to patch users, levels of cancer- causing compounds were significantly lower in patch users, indicating that medicinal nicotine is safer than snus, Hecht said. These results conflict with some prior studies that suggested that smokeless tobacco including moist snuff may be a less harmful habit than cigarette smoking because many of the carcinogens in cigarette smoke are either reduced or absent in smokeless tobacco. The bottom line, Dr.Hecht said, is that “smokeless tobacco products are dangerous.”
“The evidence suggests,” he continued, “that smokeless products are in fact a cause of oral cancer and pancreatic cancer in humans. The current evidence does not support smokeless tobacco as a substitute for cigarette smoking.”
