Effects & experience
Does kava cause a hangover?
Kava does not produce a hangover in the way alcohol does. The classic hangover — headache, nausea, dehydration, cognitive fog — is largely driven by ethanol metabolism, dehydration and acetaldehyde, and none of those apply to kava.
Kavalactones have a half-life of roughly 9 hours, so they remain in the body after the subjective effects have faded at 2–4 hours. Some people report feeling relaxed or slightly heavy the following morning, particularly after a large serving or a high-concentration extract taken late. That's a tapering effect rather than a hangover.
Alcohol
- Dehydrating
- Produces acetaldehyde as a by-product
- Typical next day: headache, nausea, fog
Kava
- Not dehydrating
- No acetaldehyde by-product
- Typical next day: nothing, or mild residual relaxation
What can still leave you feeling off: drinking kava very late, so the 9-hour half-life overlaps your morning; taking a much larger serving than usual; or combining kava with alcohol, in which case the alcohol produces its normal effects regardless.
No hangover is not the same as no effect. Kava is active for hours after you stop feeling it. Judge the following morning on how you actually feel rather than on the assumption that it must be clear.
