JLens screens out tobacco companies that derive more than 5% of their revenue from tobacco as part of its Treif (not fit for inclusion) category. This exclusion aligns with the Jewish value of preserving life (Pikuach Nefesh), which is a fundamental principle in Jewish law and ethics. The well-documented health dangers of tobacco products conflict with the Torah’s emphasis on protecting human life and health. Jewish religious authorities across denominations have generally concluded that smoking poses unacceptable health risks, making investments in tobacco companies problematic from a Jewish values perspective.
