Notes:

 Min.= minimum potency recorded; Max. = maximum potency recorded; Mean = mean potency recorded; Median= middle potency value in the ranked data set; 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) There are also data available for both sinsemilla and for other European/non-European seeded herbal cannabis: sample size 4727 and median 10.5; sample size 2762 and median 2.0, respectively. 

 (2) THC content means free THC only (without THC acid). 

 (3) 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 60, minimum 4.3; maximum 25.3 and mean 16.4.  

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

 (5) Data refer to England and Wales only. There is also data available for sinsemilla: sample size n.a., minimum 4.1, maximum 46, mean16.2, and median 15. 

 (6) There is also data available for sinsemilla: sample size 10, minimum 6, maximum 17, and mean 12.
