Notes:

 : indicates data not available 

 Min.= minimum potency recorded; Max. = maximum potency recorded; Mean = mean potency recorded; Mode = most frequent (typical) potency recorded. 

 The minimum ‘zero’ values represent a value greater than zero but lower than the minimum sensitivity threshold that allows a robust estimate. 

 (1) Data reported as mode, most frequent (typical) potency, are actually the median. 

 (2) Data reported as means is actually a weighted mean. 

 (3) Data reported as mode is actually the median. There is also data available for sinsemilla: sample size 4760; median 10 and for other European/non-European seeded herbal cannabis sample size 2453; median 2.4. 

 (4) Cannabis resin refers to imported cannabis resin; herbal cannabis refers to imported herbal cannabis. There is also data available for locally-produced herbal cannabis ('nederwiet'): sample size 53; min. 3.8; max. 23.7; mean 16.  

 (5) There is also data available for sinsemilla: sample size 10; min 5; max 22; mean 13.5.
