That is not true. It is the interaction of nicotine with various monoamine oxidase inhibitors that makes tobacco smoking addictive, to an extent that it could be stated that it is the MAOIs entirely causing the addictive behaviour: the exact same MAOIs are also found in coffee, after all.

Why are nicotine pouches and vapes addictive, then? The answer lies in the flavourings, which themselves have psychoactive properties, likely also through MAO inhibition.

God this Gwern junk will never die. There's tons [0] of evidence that nicotine is addictive on its own.

It's the nicotine.

I'm not here to argue, but all top 5 links for me are about smoking. I've not heard of people being addicted to nicotine patches for example, especially non-smokers.

No, it's because nicotine is an addictive chemical.

You will have to supply something to back up such a wild statement. Nicotine has been shown to be extremely addictive all the way from humans down to single neurons in a petri dish, for decades.
