It is really not so clear at all this is the case for pure nicotine products. See https://gwern.net/nicotine#habit-formation, and https://gwern.net/nicotine#dependence for a starter / some brief counter-evidence.

Anecdotally, I found I developed a dependence on nicotine pouches very quickly. It was also very easy to exceed the nicotine equivalent of a pack of cigarettes daily without even noticing.

But it was also easy to quit by substituting nicotine-free pouches, and withdrawal symptoms only lasted like 3 days.
