Exposure To Environmental Tobacco Smoke in an Automobile

We measured exposures to ETS in a moving minivan under three different ventilation scenarios: drivers window open/ventilation off, windows closed/ventilation on, and windows closed/ventilation off. The driver smoked a single cigarette while we measured the concentration of ETS using laser aerosol monitors and the outside air exchange rate using a tracer gas decay technique. The indoor concentrations of respirable particulate matter increased during smoking by factors of 13 to 300 depending upon the ventilation configuration. The calculated exposure for a five hour automobile trip with the windows closed/ventilation off and with a smoking rate of 2 cigarettes per hour is 25 times higher than the same exposure scenario in a residence. Smoking low tar cigarettes or operation of air cleaners or ventilation equipment cannot reduce concentrations in automobiles to acceptable levels. The most effective solution to protecting passengers from ETS exposure is not to smoke in the automobile.

The Dark Side Of Marketing Seemingly Light Cigarettes

The dark side of marketing seemingly “Light” cigarettes: successful images and failed fact

R W Pollay, T Dewhirst – 2002

Objective: To understand the development, intent, and consequences of US tobacco industry advertising for low machine yield cigarettes.

Methods: Analysis of trade sources and internal US tobacco company documents now available on various web sites created by corporations, litigation, or public health bodies.

Results: When introducing low yield products, cigarette manufacturers were concerned about maintaining products with acceptable taste/flavour and feared consumers might become weaned from smoking. Several tactics were employed by cigarette manufacturers, leading consumers to perceive filtered and low machine yield brands as safer relative to other brands. Tactics include using cosmetic (that is, ineffective) filters, loosening filters over time, using medicinal menthol, using high tech imagery, using virtuous brand names and descriptors, adding a virtuous variant to a brand’s product line, and generating misleading data on tar and nicotine yields.

Conclusions: Advertisements of filtered and low tar cigarettes were intended to reassure smokers concerned about the health risks of smoking, and to present the respective products as an alternative to quitting. Promotional efforts were successful in getting smokers to adopt filtered and low yield cigarette brands. Corporate documents demonstrate that cigarette manufacturers recognised the inherent deceptiveness of cigarette brands described as “Light”or “Ultra-Light” because of low machine measured yields.
