Kava drinking is a tradition among Pacific Island people, although growing in popularity with other ethnicities. However, drinking substantial quantities of kava has raised concerns regarding physical manifestations of slow response and lack of precision in bodily control. These impairments can have significant consequences when after consuming large volumes of kava an individual makes a choice to drive.
The objective of this study was to measure selected cognitive functions following high traditionally consumed kava volumes (greater than 2,000 mg of kavalactones) aimed at identifying potential risks for kava drink-drivers.
The reaction and divided attention of 20 control participants was assessed against 20 active kava-drinking participants during and following a 6-hr kava session in a "naturalised" setting. Assessment measures were drawn from Vienna Test System-Traffic's test battery.
RESULTS/OUTCOMES: Results showed no statistical significant difference between control and active participants at any measurement point over a 6-hr testing period regardless that the movements and speech of the active participants were observed to slow as the test session and kava consumption progressed.
Inconsistencies between test results and observations during testing and by road policing officers demonstrate an urgent need for more research in this field.
卡瓦酒是太平洋岛屿民族的传统饮品，尽管其他族裔也越来越喜欢喝卡瓦酒。然而，大量饮用卡瓦酒引起了人们对身体反应缓慢和身体控制缺乏精度等身体表现的关注。当一个人在大量饮用卡瓦酒后选择开车时，这些损伤可能会产生重大后果。
本研究的目的是测量高传统卡瓦酒摄入量（超过 2000 毫克卡瓦内酯）后选定的认知功能，以确定卡瓦酒驾驶者的潜在风险。
在“自然化”环境中，对 20 名对照参与者和 20 名活跃的卡瓦酒饮用者进行反应和分散注意力的评估，在 6 小时的卡瓦酒疗程中进行评估。评估措施取自维也纳测试系统-交通的测试套件。
结果/结果：无论在 6 小时的测试期间，观察到活跃参与者的动作和言语随着测试和卡瓦酒的消耗而变慢，结果显示在任何测量点上，对照组和活跃组之间都没有统计学上的显著差异。
测试结果与测试期间和道路警察观察到的结果不一致，这表明在这一领域急需进行更多的研究。
