I guess I knee-jerked at the need for regulation. If that regulation weeded out Noble from non-Noble, then that would be good legislation. The ban on CO2 extracts in food is not necessary, provided the source material is noble.
Hm, there are some people that claim that even CO2 might not be as safe as the traditional method.
I don't think it would make sense for NZ legislation to ban tudei as our tudei detection methods are still experimental (also note that the legislation was drafted in 2002). Besides, the real problem with tudei is that it has undesirable effects and not that it is some kind of a poison (even though we do acknowledge that it might potentially be more risky than noble kava, which appears to have a very, very good safety record).
I mean, out of all kava-specific legal acts I've seen, the NZ legislation appears as the most reasonable one. I am naturally biased, but I am happy that it doesn't prohibit my preferred types of kava products and encourages my preferred method of their consumption.
