Are Nicotine Pouches Worse Than Vaping? - Dr Andrew Huberman

The gist

1. Huberman says nicotine only boosts cognition when used once or twice a week at most; more frequent use just relieves withdrawal.
2. Vaping may be chemically cleaner per puff than smoking, but easier use means people consume far more nicotine overall.
3. Huberman notes nicotine raises blood pressure and causes vasoconstriction, which can affect sexual performance and creates problems if you try to offset it with other drugs.
4. Williamson went 1,000 days without alcohol and 500 days without caffeine to build confidence that he does not need substances to function.
