Will the sugar alcohol found in sugar free gums, sodas, sugar substitutes produce a false positive on an etg test?

No: There isn't anything in sugar substitutes that will cause the etg (ethyl glucuronide) test to show positive. However, because etg test measures products of metabolism of ethyl alcohol from any source, it is sensitive to small amounts of alcohol. It will detect ingestion or exposure to alcohol in mouthwash, cough syrup and other medicated syrups, and possibly even hand sanitizers.

NO: Sugar alcohols are merely a type of chemical compound that has -oh (hydorxyl) unit(s) attached. The etg tests for ethanol ("booze" alcohol) and it's metabolic by-products. Sugar alcohols, like xylitol and sorbitol will not trigger a positive etoh ethanol result. The benefits of artificial sweeteners is a decreased risk of cavities. Xylitol can actually decrease cavities!
