IMO the main culprit is the over regulation of semi/non-disposable vapes/nicotine which still require more R&D to make accessible and easy to use for any consumer. This disposables are just plain better because the internals of vapes are finicky. Coils, wicking, batteries, juice, all in a very small package. it’s literally easier to just throw the entire thing away than to worry about the specifics, try to buy the separate components and replace them as they age, etc. It’s why semi-disposable pod systems like juul are also quite successful.
