Selena Gomez says years of nicotine vaping have changed her voice. She spoke about the habit while discussing her decision to quit, framing the whole thing as a trade she now regrets. Her line to anyone tempted is short: it is just not worth it. The warning leans on how difficult nicotine dependence turns out to be, something she says people underestimate. For a singer, the voice is the instrument, so the toll from vaping cuts straight into her working life. Fans have watched her health become a public topic before, which gives her words extra weight with a young audience. She is not preaching so much as passing on what the habit cost her.
