Juul was/is a tobacco industry scam to make vaping more accessible and more likely to lead to tobacco addiction.
Juul started with all kinds of flavors, but then they were banned and only tobacco extract flavors were allowed.
Those extracts are more than flavor. They contain the same psychoactives which make tobacco smoking so addictive compared to vaping freebase nicotine — which Juul is not because it is an extract of tobacco nicotine salts to begin with.
I use a Juul most of the time to vape. To keep myself in cartridges, I do have to buy the Juul ones, so I get a cart full of the magic Juul juice to keep me company.
Then I refill it a bunch of times with third-party nicotine salts which taste better. It's the same thing basically.
Juul popularized using salts at high concentration with less vapor. That's about it. The rest is good product design and a fad.
