Halachic Rulings Address Used Car Sales and E-Cigarette Kashrut

Two recent halachic (Jewish law) queries address consumer and health-related issues. The first concerns the sale of a used car with a known defect. According to Rabbi Aharon Botbol, a seller aware of a specific malfunction in a vehicle must disclose it to the buyer. Relying on the buyer to discover the issue during an independent inspection is prohibited, as some defects are not easily detectable, and buyers may trust the seller's representations. While price negotiation, discounts, or accounting for repair costs are permissible, concealing a known flaw is forbidden under the prohibitions of fraud and theft.

The second query, addressed by Rabbi Moshe Sternbuch, deals with the kashrut (dietary laws) of electronic cigarettes. Rabbi Sternbuch advises using e-cigarettes with a kosher certification or ensuring their components are exclusively plant-based. Unlike traditional cigarettes that produce smoke, e-cigarettes vaporize a liquid. This liquid often contains glycerin, which can be derived from animal sources, necessitating verification of its kosher status. Furthermore, Rabbi Sternbuch cautions against using e-cigarettes on the Ninth of Av, a Jewish fast day, as the generated vapor creates moisture in the mouth, potentially constituting a form of tasting forbidden on that day.

These rulings were published in the "Achvatah" newsletter, distributed nationwide.
