Anecdata, but I am extremely addicted to nicotine lozenges.

In my anecdotal experience with common stimulants, caffeine is much more addictive and with worse withdrawal symptoms than therapeutic amounts of nicotine or amphetamine.

That said, smoked tobacco blows these out of the water and it's taken me more than a decade to kick the habit.

On the one hand, some webpage and you don't think it's addictive.

OTOH, decades of research and thousands of peer-reviewed papers, plus the authority of NIH, WHO, and FDA - to name a few - say it is highly addictive.

How many of those papers studied non smokers' nicotine patch use?

Decades of research confirmed administration route affects addiction potential generally.

Injected amphetamine is highly addictive. Many people who ingest amphetamine most days forget it some days.

Where do you come up with your 'thousands of peer-reviewed papers'? The 'some webpage' is by Gwern who usually does a pretty good job surveying the literature. I'd actually trust him over NIH, WHO and FDA here (because Gwern's smart enough to take their opinion into account where it makes sense, and also look out for their biases; not because Gwern's magically smarter than them in general.)
