"This is my first deer season," said Bob Smith, who used to chew tobacco. Before he quit, chew was Smith's best hunting buddy. While sitting silently in a tree, and watching the woods for movement for hours. "Sounds disgusting, but, it was the taste," said Smith. The taste and the addiction. Bob tried to quit for years. Willing to try just about anything, he reached for spitless tobacco. "You use the tiny pouches like chewing tobacco, but, they're small, discreet," and Dr. Richard Hurt says, "easy to like too much". "This product is a delivery system for nicotine," said Dr. Richard Hurt of the Mayo Clinic. Dr. Hurt and a team at Mayo say spitless tobacco products are not regulated. Manufacturers don't have to list what's in them. And Dr. Hurt says nicotine is only one of the ingredients. "Nicotine is part of the problem. It carries the addiction and the dependence. But, it's all the other chemicals that are present in tobacco that carry the danger. The dangers include a risk of cancer of the mouth, voice box and esophagus. It also can cause severe dental problems. Bob was quick to figure out spitless tobacco wouldn't help him quit.
