If the tobacco companies have been spending hundreds of millions on R&D for over a decade on electronic cigarettes (not necessarily vaping), which is what some of them claim, then they seriously missed the boat.
I can assure you as a long time customer they don’t have much control in the market, besides trying to buy one like Juul (Juuls are overpriced garbage by the way). There’s a thousand small businesses and shops, making very good money with tons of competition which is quickly improving the products and devices. The difference bigco R&D and launching. It’s also been a boon for Shenzen/China where all the devices are made, not just for e-cigarettes but also for marijuana pens.
But the market is in its early stages I’m sure it will evolve. I’m pretty sure it’s not even close to finished in regards to optimizing the product, they get noticeably much better each year. The anti-social giant cloud thing is also fortunately being replaced by far smaller ones thanks to Nicotine Salts replacing usual e-liquids, which is 90% smaller clouds and dissipate immediately.
Regardless of your ‘think of the kids’ plight that has nothing to do with me as an adult having responsible access to my products. I can do it with alcohol, cigarettes, firearms, and weed here in Canada. These attempts to ban entire categories of products for everyone, not just kids, are dumb. Which is exactly what they are doing.
