The good news is that I have never bought a disposable. (or a pod)
Fact is ... everything I have is 10 years old, or older.
The only thing that goes in the trash is an inch or so of wick & wire.
Being as I mix my own liquids, vaping is pretty cheap these days.
Wick & wire & a bit of paper towel is the only vape trash I have trashed in the last 10 years. Of the 6 mods that I have, one is a (regularly used) mech that is at least 8 years old, and a (regularly used) regulated mod that I've had for close to that 10 year period. I have 2 pairs each of 18650's, 18500's, and 21700's. I have an external battery charger. The lions that I use in my mods are at least 3.5 years old, and I still have a few that are older and I don't use for vaping anymore. They are used in several flashlights and little fans that I have.
My roommates' two oldest grandsons have birthdays coming up, they'll be 18 & 20. They both vape a dispo when they can. They both 'borrow' cigarettes from her when they can't. I am seriously debating with myself to get them some pods and 'vape education'.
I have already had some interesting discussions with the oldest about vaping history and facts, and he was quite surprised when I told him, and then showed him with a physical breakdown, that a mech mod and a simple regular flashlight operate the same way.
I have seen a few adult like people using dispo's instead of smoking cigarettes, and that makes me happy. Unfortunately most, probably all, of of these occurrences have been women using those things, usually right next to their smoking husband/boyfriend. I sometimes tip my hat to them, and I'm sure eventually one of the cigarette smokers is gonna say, "I only smoke REAL cigarettes", to which I'll probably reply, "And eventually you're gonna get REAL sick".
