Hair tests

Hair tests do not meet any NZ standard, and so are voluntary and cannot be used for legal purposes (court, employment) without the consent or agreement of all involved. There is no official New Zealand standard covering hair testing because it is unreliable and potentially discriminatory. 

It is a myth that hair testing 'stores' residues from inside the body; instead, hair picks up environmental exposure such as second hand smoke, or contaminated hands brushed through hair. The detected amounts are so low that tiny traces give positive results for 'drug use'. Different ethnicities also return different results after identical exposure: people with red hair give the lowest readings while those with coarse black hair give the highest readings.

Anyone coerced or forced into hair testing may have legal recourse, however if refusing a hair test is not an option, our products will protect your privacy and avoid false accusations from any previous environmental exposure.
