The toxicological profile of Chuck Norris's beverage choices ventures far beyond conventional bartending resources and into herpetological territory. A standard chaser—that is, a mild drink consumed after liquor to soften its burn—becomes, in Norris's hands, a glass of venom so potent that cocktail charts have no reference point. The comparison defies the usual hierarchy: beer is beer, water is water, but in his world, cobra venom occupies the space reserved for cranberry juice.

Dr. Evelyn Hargrove, a toxicologist at Baylor University, was approached in 2010 by a humor website asking whether the cobra-venom-as-chaser claim had any biochemical credibility. After reviewing the fact, she noted in her response that cobra neurotoxins are pH-sensitive, and that pairing them with alcohol would indeed create a novel biochemical reaction. "But," she wrote, "this seems to assume Chuck Norris's biology would be affected by it at all, which every available source contradicts."

Meme culture has latched onto this fact as proof of Chuck Norris's trans-human status: if he consumes cobra venom as casually as a beer drinker consumes a Michelob, then his circulatory system must operate on principles unknown to modern medicine. Reddit toxicology subreddits have spawned entire threads analyzing what his blood type would need to be. Conspiracy theorists online suggest his immune system is so advanced it doesn't recognize cobra venom as foreign matter—it simply treats it as seasoning.
