Announcing a New Lecture Series on Tobacco Harm Reduction

 

I am pleased to announce a new lecture series on the medical and scientific evidence for tobacco harm reduction.

This week, I am publishing “Nicotine, Correcting Misperceptions.”  The lecture is divided into an introduction and six easily digestible segments; run time and links are below. 

Nicotine, Correcting Misperceptions

Introduction     2:45  (link here)         

Comparing nicotine with caffeine, and contrasting positive and negative effects of nicotine on the brain, in the context of addiction     3:43  (link here)

Comparing nicotine delivery among combustible, smoke-free oral and aerosol tobacco and medicinal nicotine products         14:35  (link here)

Distinguishing the health effects of nicotine from those of combustible and smoke-free tobacco     14:35  (link here)

Weighing the evidence of nicotine use during pregnancy     4:00  (link here)

Investigating how the medical facts about nicotine have been exaggerated and distorted     5:00  (link here)

Valuing long-term nicotine maintenance and tobacco harm reduction     4:46  (link here)

 

You might think that you already know everything about nicotine.  So go ahead…TEST YOUR KNOWLEDGE OF NICOTINE by taking a short quiz!

You’ll get immediate feedback on your score, and the answers might prompt you to watch some of the segments.  Enjoy!

Note: While I originally created these lectures as a continuing medical education (CME) course (more information here), they do not presently convey CME credit, but are available to all who are interested in safer tobacco products for themselves, their families and friends.

I will publish the remaining topics soon.

Fake Science Denying the Relative Safety of Smokeless Tobacco Cost Millions of Lives; Don’t Repeat that Error with New Smoke-Free Products

 

Dr. Jay Bhattacharya, recently confirmed as director of the National Institutes of Health, tweeted on November 23, 2024, “If the NIH were serious about the replication crisis, it would devote a significant chunk of its budget to funding replication studies by independent researchers and require NIH funded researchers to make research materials available to replicators.”

I welcomed that statement because, over the past decade, my colleague Nantaporn Plurphanswat and I have challenged distorted and blatantly false studies concerning safer tobacco products (examples here, here, here and the list below).  Those efforts followed my earlier work with other authors on similar flawed research articles, but together they addressed only a fraction of defective FDA/NIH-sponsored tobacco research.  Because replication is time-consuming, it detracts from the performance of original research; additionally, findings are rarely published, and they often draw derision from the original authors and the research establishment. 

One might ask, why bother to address bad studies?  I answer that question in a new Sensible Medicine article titled, “Defining the Risk of Oral Tobacco Products,” in which I focus on the false narrative of a 1981 New England Journal of Medicine study that fatally undercut the fact that smokeless tobacco is vastly safer than cigarettes.  As a result of the 1981 publication, millions of smokers were denied information that could have extended their lives. 

Repeating that deadly error with vapor products, heat-not-burn tobacco and nicotine pouches will cost millions more lives.
