The impact of traditional kava (Piper methysticum) use on cognition: Implications for driver fitness

Abstract

Few studies have examined the impact of kava (Piper methysticum G. Forst. f.) on cognition when consumed at traditionally influenced volumes; most have used modified tablet-form kava, with the results erroneously overlaid on naturalistic kava consumption. Kava is a culturally significant Pacific drink with similar effects to Benzodiazepine. Traditionally influenced kava use sessions last, on average, 6 h in which attendees consume 3.6 L (7.6 pints) each of beverage kava, with some then driving home.
