Toward Less Hazardous Cigarettes

Smoke generation inside a burning cigarette: Modifying combustion to develop cigarettes that may be less hazardous to health

The formation of smoke from a burning cigarette depends on a series of mechanisms, including generation of products by pyrolysis and combustion, aerosol formation, and physical mass transfer and filtration processes. Each mechanism, and their interactions, has a profound effect on the levels of chemical constituents in tobacco smoke. An enormous amount of research has been done on these subject...

In search of the less hazardous cigarette.

Since the 1950s, despite considerable and long-term tobacco industry and government efforts, attempts to develop a less risky cigarette that reduces harmful ingredients, generally or specifically, have failed. Moreover, even under ideal conditions with adequate scientific testing, the efficacy of purportedly reducing the severe health effects cannot be scientifically verified for up to 20 years...

Reducing the nicotine content to make cigarettes less addictive

Nicotine is highly addictive and is primarily responsible for the maintenance of cigarette smoking. In 1994, Benowitz and Henningfield proposed the idea of federal regulation of the nicotine content of cigarettes such that the nicotine content of cigarettes would be reduced over time, resulting in lower intake of nicotine and a lower level of nicotine dependence. When nicotine levels get very l...

A Novel, Inexpensive and Less Hazardous Acid-Base Indicator

A new acid -base indicator which is less hazardous and inexpensive is proposed. It is capable of d istinguishing between the acids and bases. Titrations were carried out to ensure that the proposed indicator yields quantitative results. The results of titrations were quite satisfactory. The indicator was giving a distinct sustained colour even in the case of weak base and weak acid titrations. ...
