Just curious, does anyone know how disposable vapes became so popular? I feel like they went from nonexistent to everywhere in like two years. I'm interested in the history of how these things developed. Any good reads on the topic?

Good question actually. The whole disposable vape thing took off faster than most people realize. Early devices were pretty basic, low puff counts and limited flavors. Then brands started competing on battery life, flavor variety, and puff counts, and that's when things really exploded. Now you've got devices doing 100K puffs with screens and adjustable settings, which is wild compared to where they started. Fire Elf put together an interesting article tracing the whole timeline. You can learn about the evolution of disposables on their blog. The Fire Elf piece covers how different brands pushed the technology forward and why disposables overtook refillable devices for so many people. Fire Elf's blog section is surprisingly informative for this kind of stuff.
