Episode Highlights
Replacement Tactics
Nicotine replacement therapies, such as patches, gums, and sprays, offer a strategic approach to quitting smoking or vaping. explains that these methods maintain nicotine levels in the bloodstream, reducing withdrawal symptoms and cravings. He emphasizes the effectiveness of varying the nicotine delivery method to prevent the brain from expecting a consistent dopamine release pattern, similar to how casinos use random rewards to keep players engaged 1.
Nicotine replacement can be used in a similar way, but in a benevolent way, in order to help you get over smoking or vaping by keeping the total amounts of dopamine variable around the clock.

Hypnosis Tools
Hypnosis emerges as a powerful tool in smoking cessation, with highlighting its effectiveness in achieving a 23% success rate for quitting smoking. This method, developed by Dr. David Spiegel, is accessible through the Reveri app, which offers hypnosis scripts for various behavioral changes, including smoking cessation 3.
The success rate with this particular hypnosis developed at Stanford School of Medicine by Dr. David Spiegel is 23% of people who do this hypnosis one time succeed in quitting smoking.

Pharmacology
Pharmacological interventions like Bupropion, also known as Wellbutrin, play a significant role in smoking cessation. discusses how Bupropion increases dopamine levels, helping to alleviate withdrawal symptoms and improve mood, with a success rate of about 20% 6.
The outcomes with Wellbutrin for smoking cessation are pretty good if you think about an increase from 5% to 20%, that's pretty dramatic.
---
While not a one-size-fits-all solution, due to potential side effects and contraindications, Bupropion offers an alternative for those unable to use nicotine replacement therapies. Huberman also references a comprehensive review on pharmacological approaches, emphasizing the need for tailored strategies to combat nicotine addiction 7.
