I've been sitting here enjoying a snus portion and casually Googling for TSNA information. Here's a rather interesting quote from Dr. Brad Rodu:

Someone please correct me if I am wrong, but I would assume that the same rationale would apply to dry snuff. It seems that the only real harm in using American dry snuff would be if you tried to smoke a tin of the stuff. :lol:
Taking the revised TSNA levels into account, it's beginning to look as if American dry snuffs are really no more harmful than their European counterparts (e.g., J & H Wilson, McChrystals, Poschl, Toque). I will, however, leave it to a qualified expert such as Dr. Rodu to confirm or deny that particular hypothesis.
American moist snuff products in the 1980s and 1990s had higher TSNA levels, yet epidemiologic studies found that there was little risk for oral cancer. Most American and virtually all Swedish products now meet the Swedish standard for low TSNA levels, which is 10 parts per million (ppm), based on dry weight of the tobacco. Levels in Swedish products are generally around 4 ppm. Some American products are around 5 ppm, while others are in the range of 10 to 15. However, two American smokeless products, available as dissolvable pellets (Ariva and Stonewall), have TSNA levels of only 0.1 to 0.2 ppm. There is no scientific evidence supporting any measurable difference in health effects from using products with TSNA levels of 10-15 ppm versus those with 0.1 ppm. Demands on manufacturers to push TSNAs below current levels, which are the lowest in history, ought to be based on a scientific rationale incorporating some health endpoint. Otherwise, eliminating TSNAs from tobacco makes no more sense than eliminating traces of the 21 carcinogens in roasted coffee, which have not been demonstrated to confer any health risks.
