"Nicotine produces physical and mood-altering effects in your brain that are temporarily pleasing. These effects make you want to use nicotine and lead to dependence. At the same time, stopping nicotine use causes withdrawal symptoms, including irritability and anxiety".
"Nicotine meets the criteria of a highly addictive drug. Nicotine is a potent psychoactive drug that induces euphoria, serves as a reinforcer of its use, and leads to nicotine withdrawal syndrome when it is absent. As an addictive drug, nicotine has 2 very potent issues: it is a stimulant and it is also a depressant".
just two quotes from medical journals, obviously these only cover physical and mental symptoms.
There is still a lot to be said about motor function association e.g. hand to mouth movement that mimics a smoking action or chewing a pen/biting nails, are these also an addiction?
Also consider the below differences between determining if your are addicted?
A; forcing yourself to not use a PV with nicotine in it when knowingly, it is there in front of you to freely use
or,
B; physically running out of or having your PV/Nicotine taken away so you have nothing to use.
I know from prior personal experience that both these scenarios have dramatic differences on your mental state, the latter certainly causes extreme anxiety.
(I used to be a heavy drug user

(weed/cocaine) and smoker many years ago in my youth, but thankfully i was one of the lucky ones and kicked the addiction and didn't waste my life)
I find i can go a whole day without a vape if i need to and it has little effect on me, by comparison to when i was a smoker.
I have no intention of giving up vaping though!!
