> I hope we’d be exceedingly careful in what we label “addictive” in the same bucket as oxy or nicotine.

Not careful enough apparently: Nicotine isn't that addictive on its own, tobacco is.

Be aware, the vast majority of people who have ever smoked cigarettes occasionally never became addicted. They were not labeled as “smokers”. A non-trivial number of people today continue to smoke cigarettes on occasion. I like to have one on my birthday. Then again, I’m able to eat a chip and not consume the entire bag. I’m not convinced of these social science studies, and when digging into individual studies I’m sure the replication crisis comes into play.

Tobacco may be the most* addictive delivery method, but nicotine alone is also addictive. To say its not is misinformation. Consistent use of nicotine still leads to upregulation, which does cause irritability, brain fog, cravings when you stop.

* I'd even change this to say modern nicotine salts in vapes are likely to lead to dependency faster than tobacco. A 5% nicotine salt pod will contain as much nicotine as a full pack of cigarettes, and so vapers tend to consume far more nicotine in a single sitting than they ever could with a cigarette. That combined withe constant availability means users of nicotine vapes & pouches (aka, no tobacco) are likey to have a more difficult time quitting than cigarette smokers.

Bottom line, its still dangerous to dismiss nicotine's addictive potential with or without tobacco as a delivery method.

> Not careful enough apparently: Nicotine isn't that addictive on its own, tobacco is.

That is a very strong claim to make when the current scientific consensus strongly disagrees.

How does that work when nicotine products that are every bit as addictive as tobacco exist, maybe you're just not aware of them? Sitting here with non tobacco snus (Swedish nicotine pouch) under my top lip, something I have been utterly unable to quit. I believe "nicotine free" tobacco would be completely non addictive.
