Cansford Labs publishes new long-term study into what hair drug levels mean

Cansford Labs published a new research poster last week at the Society of Hair Testing Scientific meeting where it looked at the results of a study into what hair drug levels mean. Summarising the results of  nearly 15,000 hair samples taken over a 4-year study period, the research concluded that levels distributions in percentiles derived from the data samples are useful for giving relative standing of results in a large population.

The full discussion and a summary of the data can be seen on the poster here.
