Results of the quantitative determination of total thujone by NMR ( ).
Thujone content (mg/L)Number of samples found in the category

2–105 (7%)
10–3532 (46%)
>3516 (23%)
Includes several preban and illegally marketed samples. The distribution is not representative for the current market in the EU. We chose the samples to get an equal distribution over the whole range of possible thujone concentrations.
