Probably not the case for some modern pure nicotine products (gum, patches). Vaping is harder to say due to lack of data and clear cases of addiction in young people, but pure nicotine is definitely a different animal than the classical delivery forms. See my response to GP.
I wonder if the issue with vapes isn't the sweeteners they put in them. I sometimes vape a specific liquid, which has never given me any cravings. I'll just stop after my bottle is done for multiple months until I remember to buy some more. I never carry my vape with me when I leave home (not to the office, not for multi-week holidays, nothing). It's not difficult to go without, I don't even think about it when I don't have it.
But the other day I ended up vaping some melon-flavored liquid. When it was empty, I was going crazy for a few hours, I absolutely had to have more. And it didn't even have more nicotine than what I usually vape. It was just the sweet taste that had me wanting more, exactly like back in my college days when I was eating Snickers bars like no tomorrow. Now that was a habit that was tough to break. And most people I see vaping out in the street seem to be vaping those ultra-sweet smelling liquids.
I've seen multiple friends that could give up an addiction: until after a while and then they couldn't.
For many people, addictions are not that addictive until they are.
Be careful generalizing from your own experiences. Try and learn from the mistakes your (often older) peers have been taught the hardest way.
I've seen it with drinking, vaping, smoking, meth, bad partner, gambling; my friends that weren't hooked, could take it or leave it, and then one day they find they are hooked.
An interesting thought, I myself have met at least a couple people that tried to break an addiction by switching to vape products that were essentially just flavour (no nicotine, no THC; THC vapes are common and legal in Canada) and somehow stayed just as addicted to the flavour / oral stimulation. So that sounds at least plausible to me.
