I switched to vaping to quit tobacco and at that point in time they only had mech mods. It started with the copper tube’s and then you progressed to the box mods. It was pricey and you had to have a basic understand of electronics in order to make coils and get things to work but it was actually enjoyable. I was able to stop vaping far easier than smoking, but now when I look at the vape industry all of that is gone. It’s stupid easy to get and use the tapes and on one hand it’s great for those wanting to quit smoking, but it makes it far too easy for people who never smoked to get into it. The specialty shop i went to wouldn’t let you walk out with the mods without demonstrating you could use it safely and knew the bare minimum about how the circuit worked. Now you can just walk into a gas station and buy a disposable that ultimately contributes to electronic waste.
