‘Doped’ on Kava: Understanding Kava’s Impacts on Cognition and Driving

S. ‘Apo’ Aporosa (PhD).

This study considers kava (Piper methysticum G. Forst. f) and its effects on cognitive functioning when consumed traditionally. Kava drinking continues to play a dominant role in the cultural practices of many Pacific peoples, whether in their home environments or new diasporic communities. The relaxant and soporific effects resulting from lengthy kava use make it popular among non-Pacific users, too, as a ‘social lubricant’ and alternative to alcohol. Driving between kava venues after lengthy kava use has become routine among both traditional and new users. The deterioration of cognitive function, including kava’s potential impacts on driver performance, has not been researched in depth until now.
