Juul fails to properly report clinical trial results

Drug and medical device companies have a long history of selective reporting the results of clinical trials used to test their new products and even of burying results they don’t like. In an effort to make it harder for companies to manipulate reporting of results, the federal government (NIH) created ClinicalTrials.gov, where companies and othersContinue reading “Juul fails to properly report clinical trial results”

More details on how menthol helps Big Tobacco keep kids hooked

Keeping menthol in cigarettes (and other tobacco products) has been a priority for the tobacco companies ever since they got it exempted from the characterizing flavor ban in the 2009 Family Smoking Prevention and Tobacco Control Act that gave the FDA jurisdiction over tobacco products. The already-strong case for banning menthol just got stronger withContinue reading “More details on how menthol helps Big Tobacco keep kids hooked”

More direct evidence that SF flavor ban worked

Last year we published a paper on implementation of San Francisco’s ban on the sale of flavored tobacco products (including menthol) that reported that health department inspectors found high compliance with the flavor ban when they visited retailers.

We know a lot about how e-cigarettes cause disease

The evidence on the health effects of e-cigarettes was the subject of two recently published reviews that focus on cardiovascular, pulmonary and immunologic effects of e-cigarettes. These reviews complement earlier reviews on the pulmonary effects of e-cigarettes, e-cigarettes and smoking cessation, and the gateway effect for smoking among youth and young adults.

What we can and cannot say about the immediate effect of SF’s flavored tobacco product ban

NOTE: This blog post was written before it came to light that the San Francisco data in the Friedman study was all collected before the flavor ban was being enforced. Without data after enforcement started, Friedman’s paper falls apart. Please read the recent blog post detailed why this is the case. On May 24, 2021Continue reading “What we can and cannot say about the immediate effect of SF’s flavored tobacco product ban”

Can you believe the papers in the AJHB issue Juul financed?

When I wrote “Surprise! Juul publishes a paper concluding that e-cigs save lives” criticizing a paper in American Journal of Health Behavior for being based on questionable risk estimates, my first draft said I was surprised that the paper got past independent peer reviewers. But then I realized that all but one of the 13 papersContinue reading “Can you believe the papers in the AJHB issue Juul financed?”

CDC’s new mask guidance and why FDA CTP should not assume e-cigs help smokers quit in the real world

On May 13, 2021 the CDC lifted most restrictions on the use of masks for people fully vaccinated against COVID-19 (two weeks after the second shot for Pfizer or Moderna and 1 week after J&J). While some people thought this was a political decision, CDC Director Walensky explained in detail that real world experience showedContinue reading “CDC’s new mask guidance and why FDA CTP should not assume e-cigs help smokers quit in the real world”
