assumtions of cigarette smoke and a lead from the future

although the chemistry of the smoke will constantly change by seemingly infinitesimal reactions taking place as they may and are afforded the opportunity, without rigorous mathematical analysis it would seem there might just be a possibility the molecules rearrange themselves in fashions that are actually more safe than their lesser burned counterparts.  intuition tells me this is unlikely in the case of tobacco smoke, at least indefinitely.  But maybe under the right conditions there might just be some godly molecule that makes the world happy?
