Understanding NRT Efficacy: Relative vs. Absolute Quit Rates
Initial Discussion on Nicotine's Cognitive Benefits
2 Key Concepts
Nicotine Replacement Therapy (NRT)
NRT is a method designed to help people quit smoking by delivering nicotine through various products like gums, patches, lozenges, or sprays, without the harmful chemicals found in tobacco. It aims to alleviate withdrawal symptoms and cravings, making it easier to stop smoking.
Absolute vs. Relative Efficacy
When evaluating the effectiveness of an intervention, relative efficacy describes the percentage change in outcome compared to a baseline, which can sound significant. Absolute efficacy, however, states the actual difference in outcome rates, providing a more realistic measure of the intervention's true impact.
4 Questions Answered
No, the U.S. Surgeon General and the World Health Organization (WHO) have found inadequate evidence to infer a causal relationship between nicotine exposure and cancer risk. The numerous carcinogens are primarily found in tobacco smoke, not nicotine itself.
NRT increases the chances of successfully quitting smoking by about 50-60% in relative terms. However, the absolute quit rate at six months for people trying to quit smoking is generally low (3-5%), meaning NRT may increase this absolute rate by only 2-3 percentage points.
Tobacco plants contain nicotine, which is the addictive component, but they also contain at least 69 other chemicals that are identified carcinogens. Nicotine itself, unlike these other tobacco chemicals, is not considered a carcinogen.
The episode explores potential benefits, such as improving cognition and aiding in weight loss. Peter Attia personally found intermittent nicotine use beneficial for focus and mental sharpness.
9 Actionable Insights
1. Quit Smoking for Longevity
If you are a smoker and interested in improving your longevity and health, prioritize smoking cessation as it is the most impactful and fundamental step you can take.
2. Distinguish Nicotine from Tobacco
Understand that nicotine, in isolation, is not identified as a carcinogen by health organizations, unlike the numerous cancer-causing chemicals found in tobacco smoke.
3. Utilize NRT for Smoking Cessation
If trying to quit smoking, consider using Nicotine Replacement Therapy (NRT) products like gum, patches, or lozenges, as they can increase your chances of successfully quitting by 50-60% (relative increase).
4. Combine NRT and Wellbutrin
For enhanced effectiveness in smoking cessation, consider combining Nicotine Replacement Therapy (NRT) with Wellbutrin, an antidepressant, as part of a comprehensive strategy.
5. Assess Absolute vs. Relative Risk
When evaluating the effectiveness of health interventions, always ask for the absolute success rate or improvement, not just relative increases, to understand the true impact.
6. Vary Deadlift Exercises
Incorporate variations of deadlifts, such as sumo, standard, and hex bar, into your routine and alternate them to keep your training fresh and effective, as deadlifts are considered a fundamental exercise.
7. Use Long Socks for Deadlifts
Wear long high socks when performing sumo deadlifts to protect your shins from injury, as demonstrated by Peter’s experience of ripping his shins without them.
8. Consider Nicotine for Focus
If considering nicotine for cognitive benefits like sharpening focus, start with very low doses (e.g., 2mg lozenges or pouches) and proceed cautiously, as it can cause nausea and has an addictive nature.
9. Park Nicotine Gum/Lozenges
When using nicotine gum or lozenges, chew it a little to release nicotine, then ‘park’ it in your mouth rather than continuously chewing to avoid nausea.
3 Key Quotes
The US Department of Health and Human Services says they've identified at least 69 chemicals contained within the tobacco plant, i.e. things that make it into cigarettes that are carcinogens, and nicotine is not one of those things.

If you're a smoker and you're interested in longevity, there's harder to find a lower hanging piece of fruit than smoking cessation.
Peter Attia
Nicotine makes up, it says about one to 3% of the dry weight of tobacco. Whereas these nightshades, it's like millions of a percent, very trace amounts.
