They found the level of cotinine, which is a marker for nicotine exposure, was 0.043 nanograms/milliliter (ng/ml) in nonsmokers, compared to about 180 ng/ml among smokeless tobacco users, about 131 ng/ml among cigarette users and about 184 ng/ml among people who used both smokeless tobacco and cigarettes. Probably the most popular method of risk reduction is switching to low nicotine tobacco. Unfortunately, most techniques used to reduce the risk don’t work, and, in many cases, may actually increase the dangers of chewing. Using data from blood and urine samples, they looked for markers used to measure the addictive stimulant nicotine and cancer-causing NNK. Dippers are always looking for ways to reduce the health risks of chewing. While it had been suggested that users of smokeless tobacco are exposed to high levels of nicotine and cancer-causing agents, there were few studies looking at those levels in people across the U.S., they write.įor the new study, the researchers analyzed information from 23,684 participants in national health surveys between 19. adult males between 20, the researchers write in Cancer Epidemiology, Biomarkers and Prevention. Smokeless tobacco - which includes chewing tobacco, snuff, dip, snus and dissolvable tobacco - was used by about 7 percent of U.S. “Even types of tobacco that may be theoretically safer because of their mode of delivery really depend on user specific details,” such as how much and how long people use tobacco products. “There really is no safe form of tobacco,” he told Reuters Health.
Patches, gum and inhalers are all types of alternative nicotine sources, said Leone, who wasn’t involved with the new study. “There are much safer ways to substitute sources of nicotine.” Frank Leone, who is director of the University of Pennsylvania’s Comprehensive Smoking Treatment Program in Philadelphia. “It’s not uncommon for people to use smokeless tobacco as an alternative to cigarettes in an attempt to wean themselves off smoking,” said Dr. Reported by: Univ of Miami Florida Office of Tobacco Control, Florida Dept of Health.
Hawken chewing tobacco nicotine content free#
The percentage of free nicotine varied from a mean value of 0.23 (Hawken Wintergreen) to 68.14 (Kodiak Wintergreen) ( Table 1 ). More research is needed on the toxic components of smokeless tobacco products and the health of people who use them, write the researchers from the Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention. Mean free nicotine levels varied from 0.01 mg/g (Hawken Wintergreen) to 6.23 mg/g (Copenhagen Snuff). Assuming 23.8 mg/g MS in SLT, SLT use at 15 g/day, 100% bodily absorption of the MS, and 60 kg body weight, the average daily intake would be 6.0 mg/kg-day, i.e., 12x the acceptable daily intake (ADI) of 0.5 mg/kg-day established for this compound by a joint FAO/WHO committee.(Reuters Health) - Compared to cigarette smokers, users of smokeless tobacco are exposed to equal or higher levels of nicotine and NNK, a cancer-causing chemical in tobacco products, according to a study from the U.S. For hard candy, a reported average of maximum use levels is 2.0 mg/g (Burdock, 2009). The average of the five highest SLT MS levels was 23.8 mg/g, i.e., 5x higher than the level found in the confectionery product with the highest MS level (LifeSavers Wint O Green Sugar Free, 4.6 mg/g). Of the "wintergreen" SLT, "Hawken Wintergreen" was found to contain the highest methyl salicylate (MS) level (29.7 mg/g). Richter and her colleague Francis Spierto, PhD, analyzed 18 brands of smokeless tobacco to determine their free-base nicotine content. For hard candy, a reported average of maximum use levels is 2.1 mg/g (Burdock, 2009). Tobacco companies are required to report the amount of nicotine in their smokeless tobacco products to the CDC, but by law this information is kept confidential as proprietary information. The average for the most five most-highly mentholated confectionery products was 3.5 mg/g. Of the "mint" SLT, "Timberwolf Packs Mint Pouches" contained the highest menthol level (5.3 mg/g) the average for the five most-highly mentholated SLT products was 4.3 mg/g. Also analyzed were "mint"-related and "wintergreen" confectionery products. Nicotine and flavorant compound levels were measured in 10 "mint"-related sub-brands and 8 "wintergreen" sub-brands of smokeless tobacco (SLT).
