Standardized storage experiments with hashish and its isolated pure components have shown that for the judgement of hashish samples a comparison of total values of CBD/CBDA, CBN/CBNA and THC/THCA is important. The investigation is carried out by HPLC and is illustrated by a histogram obtained with the aid of a simple data processing program. Changes in the individual cannabinoid contents resulting through different storage conditions are largely compensated for. These results should be confirmed through an additional comparison with standardized HPLCs calculated on the basis of the same weight‐in quantity. This is demonstrated on five different confiscated hashish samples.
