Why are caffeinated alcoholic beverages especially risky?

CONCLUSIONS: These findings do not support the masking hypothesis. Caffeine was strongly associated with ARCs when consumed at high doses and this effect does not appear to be the result of drinking more alcohol or underestimating one's blood alcohol content. Efforts to reduce caffeinated alcohol beverage use are greatly needed. PMID: 31377447 [PubMed - as supplied by publisher]
