In this “Ask Me Anything” (AMA) episode, Peter and Bob dive deep into nicotine, a complicated and interesting molecule that has effects on both the brain and the body. They analyze the results of the studies that describe nicotine’s cognitive benefits and potential for inducing weight loss. They talk about a smoking cessation technique called nicotine replacement therapy and give a full breakdown of the various routes of administration, dosing, and safety. Finally, they explore the fascinating and counterintuitive observation that cigarette smokers are less likely to get a severe case of COVID-19.
