It's all about the nic hit. The addcition / reward pathway (dopaminic) center in your brain makes you think you need flavors and big clouds etc if you're not giving it enough nic.
think about it - this same system once made you think (when you had you FIRST cigarette) that sucking that burned paper and dried leaves was a tasty thing to do.
You could up your nic content to 35mg and any flavor, literally turd flavor or car exhaust fume flavor, with just a modest amount of vapor would make you happy.
Try it and see.
Addiction=repeated experiences= what we call habit.
I have a back up $1 pos cig-alike I got in a market in China with really high nic carts. The vapor is poor, it tastes awful and on the exhale there is next to no vape. Still satisfies tho - due to my brain saying 'yup, that's the stuff we want, right there pal...'
Of course I upgraded due to
juice limitations and the damn thing running out of battery every hour or most of the carts giving only 3 puffs then dying....
