An Assesment of Twenty-Four Brands of Cigarette from the Swiss Market with Regard to the Retention of Particulate Matter and Nicotine in the Human Respiratory System
Length: 4 pages

Evaluates the retention of total particulate matter [TPM] and nicotine in a human subject and states the objective is to determine which design parameters minimize TPM deposition in the respiratory tract. Finds some humectants increase TPM retention, states ventilation decreases TPM retention and says additional research on the effects of humectants is necessary.
N.B.: Test was performed using a single human subject.
- Inhalation ProfileAre cigarettes designed to cater to individual inhalation profiles?
- Low-yield cigarettesModification of low yield products to assure that adequate levels of nicotine delivery are maintained, and effects of yield changes on toxicity and dependence.
- Measuring human intakeDevelopment of scientifically valid procedures for measuring tar and nicotine levels that more accurately reflect human intake.
- Smoking psychology and behavior
- Use of tobacco processing/ blendsModification of tobacco products through changes in tobacco processing and use of blends, and measuring effects on dependence, behavior, and toxicity.
