Some wines contain the carcinogen urethane. The wine equivalent of 1 ounce of pure ethanol per capita per day has been cited as healthful to adults to relieve stress and promote relaxation. However, it is often abused, which can lead to habituation with consequent liver damage, malnutrition, and a wide variety of other physical and mental problems, including the development of cancer. Some of the additives to wines have been known to cause allergic reactions in humans.
