Problems with the Tobacco Products Scientific Advisory Committee (TPSAC) List of Harmful or Potentially Harmful Tobacco and/or Tobacco Smoke Components

Reduced Exposure to Harmful and Potentially Harmful Smoke Constituents With the Tobacco Heating System 2.1

INTRODUCTION Heating rather than burning tobacco reduces levels of harmful and potentially harmful constituents, and consumer products using this approach aim to reduce exposure to tobacco toxicants. The Tobacco Heating System (THS) version 2.1 has been enhanced from earlier prototypes with an improved heat control and sensorial experience and thereby user acceptance. Exposure measurements are ...

Identification of Active Components in Tobacco Smoke

You might as well smoke; the misleading and harmful public message about smokeless tobacco

BACKGROUND Compared to smoking cigarettes, use of Western smokeless tobacco (ST) products is associated with a very small risk of life-threatening disease (with estimates in the range of a few percent of the risk from smoking, or even less). This means that smokers can realize substantial health benefits by switching to ST, an obvious substitute. But consumers and policy makers have little chan...

Biological activity of tobacco smoke and tobacco smoke-related chemicals.

Exposure to whole cigarette smoke from reference cigarettes results in the prompt (peak activity is 6 hrs), but fairly weak (similar to 2 fold), induction of murine pulmonary microsomal monooxygenase activity. This activity can be detected by using as substrates either benzo(a)pyrene or ethoxyresorufin, and can be inhibited by treatment with cycloheximide or actinomycin D. Unlike the induction ...

Nitrogen Transformations in the Tobacco Float Tobacco System

In order to investigate the possibility of using organic fertilizers in tobacco floating nursery, an experiment was conducted at tobacco research institute of Urmia in 2010. The experiment was done as factorial trail based on randomized complete block design (CRBD) with four replications. The levels of first factor were disinfected poultry manure, disinfected pigeon manure, a complete fertilize...
