Helen Poulsen

ESR
Dr Helen Poulsen works in the Toxicology Section of ESR, based in Wellington. She has over twenty years of experience in analysis of drugs and poisons in biological specimens and their involvement in accidental or unexpected sudden death. The work of the Toxicology group is principally related to coronial and criminal cases. But prior to that, for 14 years, she was part of the illicit drugs group of DSIR/ESR analysing exhibits from police seizures. This was back in the 1980s when cannabis was a major drug of concern for the police. With research experience in the areas of the potency of cannabis and cannabis product in New Zealand, she was involved in discussions with MOH and Police prior to hemp being allowed to be grown in NZ. She also analysed the hemp grown in the first few years to determine the THC levels. More recently Dr Poulsen has been part of a committee evaluating the impact of hemp seed based foods on roadside oral fluid testing.
ESR has developed methods for extracting cannabinoids from various matrices, looking at levels of THC, CBD and CBG and their acid forms.
