Nicotine alone can reduce hunger, even though smoking is bad because of other chemicals.
Scientific Claim
Nicotine acts as an appetite suppressant via central nervous system activation of hypothalamic satiety pathways independent of tobacco-derived toxins.
Original Statement
“Nicotine directly is not that bad. It's more so about the other things that are in most tobacco products and things like that.”

The appetite‐suppressant effect of nicotine is enhanced by caffeine *
This study found that nicotine alone (without smoking) makes people feel less hungry and more full, which supports the idea that nicotine itself, not just smoke, suppresses appetite.
GLP-1 and nicotine combination therapy engages hypothalamic and mesolimbic pathways to reverse obesity
This study found that nicotine, when given with a weight-loss drug, makes mice eat less by activating brain areas that tell them they’re full—without using any tobacco chemicals.
Contradicting (1)
Nicotine chewing gum for the prevention of postoperative ileus after colorectal surgery: a multicenter, double-blind, randomised, controlled pilot study
This study didn’t look at whether nicotine makes people feel less hungry—it looked at whether nicotine gum helps people’s guts recover after surgery. It found no benefit, so it doesn’t support the idea that nicotine suppresses appetite through the brain.
