Menthol: A Hook for Young Smokers

New research from the Harvard School of Public Health shows that tobacco companies have been deliberately varying levels of menthol in their cigarettes, marketing cigarettes with lower levels of menthol to younger smokers and then increasing the level of menthol with the age of the target demographic. From the article:

One document from R.J. Reynolds noted that all three major menthol brands "built their franchise with YAS (younger adult smokers) ... using a low-menthol product strategy. However, as smokers acclimate to menthol, their demand for menthol increases over time."

In 1987, R.J. Reynolds marketed low-level menthol varieties to persuade consumers to switch from regular brands and to recruit new, young smokers, noting: "First-time smoker reaction is generally negative. ... Initial negatives can be alleviated with a low level of menthol."

This new research serves as a reminder that, despite famous regulations about where and how Joe Camel can be displayed, tobacco companies continue to market deadly products to very young people.

New Report Suggests CT Scans may become Cancer Risk for Children

A new report in today's New England Journal of Medicine suggests that many people in the U.S. are needlessly exposed to dangerous radiation during medical tests, particularly CT scans. The problem is most clearly evident with respect to children. The report may be overestimating possible risks to adults, but there is a clear reason to think that an excess of these tests pose a public health risk to children.

The study points out that a minimum of 4 million CT scans are done on children per year, with over 62 million done on the American population as a whole. These large numbers are the result of the overwhelming popularity and rapid increase of use of CT scans since they were introduced. These numbers, in conjunction with studies showing that a large percentage of medical tests are completely unnecessary, suggest that many children are being given CT scans when they do not need them.

The risk of CT scans come from the "super X-rays" that the test uses. Children are more susceptible to radiation than adults and more likely to develop cancer because of it. But it is important to remember that the risk to any one particular individual is slight. It is only when we look at large populations that a problem starts to emerge. It is also important to remember that the report is pointing to a potential problem rather than an actual one: the report predicts that CT scans will be tied to a significant percentage of cancer cases. This means that the new report gives us an opportunity to head off a public health problem before it becomes truly dangerous. It also highlights one of the possible downsides of rampant overuse of medical tests.
