Vapoter sans nicotine : est-ce un péché dans le judaïsme ?

Judaism's framework reaches the same bench from its own texts. Shmirat haguf — guarding the body — is derived from 'guard your lives' (Deuteronomy 4:9) and the parapet law's hazard-removal principle (22:8), and modern poskim have used exactly this framework for smoking: Rav Moshe Feinstein's famous arc — from cautious permission when tobacco's harm was debated to strong discouragement as evidence mounted — is the template every subsequent vaping responsum cites. Applied to zero-nicotine vapor: permitted now, with a built-in ratchet — as evidence of pulmonary harm firms up, the permissibility narrows, because 'one may not rely on a miracle' (Pesachim 64b) covers both theology and toxicology. There is also a distinctly Jewish productivity question: bitul zman (wasted time) and the cloud-culture social scene raise the same mild flags the tradition raises about any leisure habit with paraphernalia. The practical halakhic counsel: the ex-smoker using zero-nicotine devices to quit has the strongest case; the never-smoker adopting a hand ritual with untested aerosols for fun has the weakest; and the prudent — 'the prudent sees danger and hides himself' (Proverbs 22:3, quoted in Jewish sources as well) — wait for the epidemiology before enlisting.
