Some people compare kava favorably to alcohol on this point, and there's something to that — but we want to answer precisely rather than with a flat "never."
What's generally true
Traditionally prepared, moderate kava consumption is not commonly associated with the kind of next-day symptoms — dehydration, headache, nausea — that a heavy night of alcohol can produce. Kava is a mild diuretic, so staying hydrated is a reasonable precaution, but this isn't the same mechanism that produces an alcohol hangover.
What we're not going to claim
We're not going to tell you a kava hangover is impossible. Drinking a large amount, particularly of a heavier or non-Noble preparation, can leave some people feeling groggy or sedated the next day. Non-Beverage Grade (tudei) kava in particular has a real reputation among drinkers for longer-lasting, less pleasant next-day effects — which is one of several reasons it's not something we sell.
On telling noble from tudei
This article previously described a color test for distinguishing the two. That's not an accurate way to classify kava — grade is determined by chemotype and flavokavain content through actual lab analysis, not a color change.
