Risks Being Studied
Once again history sees the nicotine cart out before the horse. While smoking harm reduction advocates point to smokeless tobacco as "safer" than smoking, to date none have been able to tell us what "safer" really means.
Until now nearly all tobacco research funding has been directed at smoking. But a flood of new products into the smokeless tobacco market at last have researchers beginning to examine the long-term costs of spending years in chemical bondage to smokeless tobacco. This thread will be home to their findings.
Let us not forget that while smoked nicotine generates more than 4,000 chemicals, unadulterated oral tobacco contains at least 2,550 chemicals. While 81 potential cancer causing chemicals have so far been associated with smoking up to 28 potential carcinogens have been found in oral tobacco.
