What are some concerns about using PREPs to reduce harm?
Scientists must first understand what a “meaningful” reduction in exposure means, and who might benefit from this type of reduction. Scientists must know: • If an individual has a history of smoking • How long the smoking lasted • What medical problems the individual has • The individual’s gender and racial or ethnic differences, which might result in different uses and effects of PREPs. One of scientist’s main concerns is that because of the many differences among individuals and how they might use PREPs, a claim about PREPs will not be relevant for everyone. Another major concern is that claims by tobacco companies that their products result in less exposure may confuse or mislead consumers. For instance, if a smoker believes that less exposure means fewer chances for disease, they might decide to continue smoking rather than quit. Or, former smokers may resume smoking. This might result in increased tobacco-related disease. Another concern is that while a PREP may reduce one toxin o
