'PREPs': future or folly?
John Britton
Abstract
PREPs, or potential reduced exposure products, are alternatives to conventional cigarettes presented by the tobacco industry as a means of reducing the risk of smoking. PREPs fall into two broad categories: those based on a conventional cigarette design but using tobacco that has been modified to reduce toxin levels, or using more effective filters, or both; and those based on completely novel designs involving the heating rather than burning of tobacco or other material.
There is evidence that some of these products are associated with lower levels of carcinogen exposure, but the practical relevance of this in terms of individual or public health is unknown. In this presentation I will review the main products, the evidence on their effects on exposure, and discuss the regulatory deficiencies and public health questions their development identifies.
