When people talk about vaping today, it feels so mainstream, but it actually started out back in the early 2000s with the idea of offering a “cleaner” alternative to cigarettes. I remember my college roommate getting his first e-cig—it looked like a pen and he thought it was some cool gadget. Fast forward, he ended up using it more than regular smokes. That’s the tricky part: something meant as a substitute often becomes its own habit. If you’re digging into the history, it’s worth also looking at long-term risks—this article really opened my eyes: Does vaping really cause cancer?. Shows how what started as “harm reduction” can still have hidden dangers.
