You get the impression that Juul invented vaping not mentioning the previous inventors. Many products and vapers were already using vaping for harm reduction vs cigarettes.
Juul only created a product the consumer couldn’t decrease the amount of high nicotine they were sold. Juul created the ability to easily market and sell to minors. This gravely hurt current and future adults trying to quit smoking.
Many adults use vaping to quit. It’s so much safer than smoking. Not totally harmless but much safer. Many middle age smokers use flavors to quit smoking because they wanted to get away from tobacco flavor to reduce the cigarette desire. The UK encourages vaping for harm reduction. Please look at UK science studies on vaping.
I wouldn’t say Juul were great innovators. They led to the US government demanding more people die from lung cancer by outlawing vaping. The anti-vape groups rightly concerned about youth throw adults under the bus.
