The concerns about the adverse effects of non-noble varieties, produced by their undesirable composition of kavalactones and high concentrations of potentially harmful compounds (flavokavains, which are not present in any significant concentration in the noble varieties), have led to legislation prohibiting exports from countries such as Vanuatu. Likewise, efforts have been made to educate non-traditional customers about the difference between noble and non-noble varieties and that non-noble varieties do not offer the same results as noble cultivars. In recent years, government regulatory bodies and non-profit NGOs have been set up with the declared aim of monitoring kava quality; producing regular reports; certifying vendors selling proper, noble kava; and warning customers against products that may contain tudei varieties.
