A Progress Report on Acid-Induced Nicotine Migration

Abstract

Reports results of nicotine migration studies "as induced by the presence of malic or tartaric acid." Indicates "impregnation of cigarette paper with acid can cause migration of nicotine to the periphery" causing elevated nicotine delivery into mainstream smoke." Tests levels of nicotine migration and constituent yields based on tobacco and paper types, and other factors.

Hypothesis

Design changes over time

Changes in cigarette design over the past half century.

Free Nicotine

Introduction of new/unconventional products

Research and development of novel nicotine delivery devices and experimental tobacco designs.

Mainstream constituent yields

Modification of selected mainstream smoke constituents in response to health concerns.

Nicotine transport, transfer, and uptake

Design changes which alter nicotine delivery or effect how the product causes and maintains dependence, including transfer of nicotine from tobacco to smoke, and uptake into the body.

Use of filters, paper, and ventilation

Modification of tobacco products through use of filters, paper, and ventilation, and measuring effects on dependence, behavior, and toxicity.
