Traditional kava-drinking, cognition, and driver fitness

Abstract

Kava, or ‘the plant of the gods’, grows widely across tropical Moananuiākea (the Pacific). Used in traditional medicine, its roots are also ground and steeped in water to make a drink with relaxant effects. Kava has deep cultural significance, but because it is customarily consumed in large quantities over several hours, concerns have been raised about its effects on driver safety. Dr ‘Apo’ Aporosa, a Research Fellow at the University of Waikato in New Zealand, has studied the impact of traditional kava use on cognition and its implications for driver fitness.
