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 sinsemilla: sample size = 5516 and median = 10.9.
(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 = 58; min = 7; max = 21.3 and mean = 15.5.
(4) Data reported as means is actually a weighted mean.
(5) There are also data available for sinsemilla: sample size = 303, min = <0.2, max = 30, mean = 8, median = 7 and mode = 1 and other European/non-European seeded herbal cannabis: sample size = 254 min = <0.2; max = 19, mean = 2, median = 1 and mode = 1.
