Most of you have noticed that, as you get closer and closer to the end of a cigarette, each puff tastes more and more powerful or intense. That’s because it is; there are more active ingredients in those later puffs. There’s an enormous amount of scientific data about tobacco cigarettes because big tobacco companies and the Public Health Community have been studying cigarette potency since the 1950s. Those studies show that the amount of nicotine increases puff-by-puff to about three times the concentration, from the first puff to the last puff. By the same laws of physics, all different types and strains of smokeable products will react the same so there’s likely to be much more intensity in the last puff than the first puff, maybe as much as three times more. That’s why being able to smoke that last puff is so important and why The AXIS 2000 Clip is so useful.
