Alcohol and Kava: what the published research says

PubMed indexes 8 records that name Alcohol and Kava together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.

Read this first

An evidence index, not guidance.

Every statement below is attributed to a named, dated, linked source.

This page lists published research relevant to Alcohol and Kava. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.

The research

8 studies naming Alcohol and Kava.

Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.

Is kava alcohol?: The myths and the facts.

Pacific health dialog · 2011 · PMID 23008981

Comparative StudyHuman subjects

“The paper concludes with a discussion of the historical influences that have promoted some of the misconceptions surrounding kava. Ultimately the paper demonstrates that kava and alcohol are entirely different kinds of beverages with different effects, and that lingering misconceptions can be seen as a 'colonial hangover'.”

Aporosa · From the abstract

Names both Alcohol and Kava in its title.

'From Kava to Lager'--alcohol consumption and drinking patterns for older adults of Pacific ethnic groups, and Europeans in the Diabetes Heart and Health Study (DHAHS) 2002-2003, Auckland New Zealand.

Pacific health dialog · 2009 · PMID 19585734

Comparative StudyHuman subjects

“Middle-aged and older Pacific adults are less likely to consume alcohol than Europeans however those who drink consume more on a typical occasion but drink less regularly resulting in lower weekly consumption of pure alcohol. Drinking patterns in these Pacific adults tend to show substantial diversity by age (older are less likely to drink), sex (women less likely to drink), and financial deprivation (middle groups consume more than least and most financially deprived).”

Sundborn et al. · Authors' conclusion

Names both Alcohol and Kava in its title.

Parameters of kava used as a challenge to alcohol.

The Australian and New Zealand journal of psychiatry · 1986 · PMID 3460587

Case ReportsHuman subjects

“Do the kava pyrones possess anxiolytic or antipsychotic properties? Do they indeed have the property for which Pacific missionaries introduced them to Australia, as an alternative to alcoholism?”

Cawte · From the abstract

Names both Alcohol and Kava in its title.

Kava, alcohol and tobacco consumption among Tongans with urbanization.

Social science & medicine (1982) · 1982 · PMID 7100955

Comparative StudyHuman subjects

“It appears that kava, a traditional Pacific beverage may have lost ground to alcohol as urban Tongans adopt a more cosmopolitan life style. Kava, if proved relatively harmless, may be promoted as a less unhealthy alternative to tobacco and alcohol.”

Finau et al. · From the abstract

Names both Alcohol and Kava in its title.

Factors related to smoking and consumption of alcohol and kava in children attending the upper grades of primary schools in Vanuatu

[Nihon koshu eisei zasshi] Japanese journal of public health · 2014 · PMID 25746933

Human subjects

“Our results indicate that the food consumption, attitudes toward smoking and consumption of alcohol and kava, and family members' smoking status were associated with the participants' smoking and consumption of alcohol and kava. In conclusion, it may be necessary to consider these factors when establishing measures to prevent smoking and consumption of alcohol and kava among primary school students.”

Nakaseko et al. · Authors' conclusion

Names both Alcohol and Kava in its title.

Role of ethanol in kava hepatotoxicity.

Phytotherapy research : PTR · 2010 · PMID 19943335

ReviewHuman subjects

“Alcohol is often co-injested in kava hepatotoxicity cases. This review evaluates the possible hepatotoxicity mechanisms involving alcohol and kava.”

Li et al. · From the abstract

Names both Alcohol and Kava in its title.

Kavalactones fail to inhibit alcohol dehydrogenase in vitro.

Phytomedicine : international journal of phytotherapy and phytopharmacology · 2006 · PMID 16428028

“This present study investigated whether pharmacokinetic interactions between kava constituents and alcohol via alcohol dehydrogenase (ADH) inhibition by individual kavalactones might explain its claimed hepatotoxic effects. Four kavalactones, (+/-)-kavain, methysticin, yangonin and desmethoxyyangonin, fail to inhibit ADH in vitro at 1, 10 or 100 microM concentrations.”

Anke et al. · From the abstract

Names both Alcohol and Kava in its title.

What this evidence cannot tell you.

Search-based evidence indexes have real limits, and it is worth being explicit about them:

NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers Alcohol, Kava, and several hundred other substances.

The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
