Notes:

Min. = minimum purity recorded; Max. = maximum purity recorded; Mean = mean purity recorded; Median = middle purity value in the ranked data set; Mode = Most frequent (typical) purity 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 provided for purity of methamphetamine is given in content in mg per tablet/unit: Sample size = 25.; Min = 0,3; Max = 81; Mean = 29,1; Median = 24; Mode = 37,7.

(2) Data provided for purity of methamphetamine is given in content in mg per tablet/unit: Sample size = 24813.; Min = 7; Max = 14; Mean = n.a; Median = 112; Mode = n.a.

(3) Data provided for purity of ecstasy is given in % of MDMA: Sample size = n.a; Min = 0.4; Max = 67.5; Mean = 26; Median = n.a; Mode = n.a.

(4) Data provided for purity of ecstasy is given in % of MDMA: Sample size = 33; Min = 19.1; Max = 83.75; Mean = 63.4; Median = 79.66; Mode = n.a.

(5) The amphetamine sample contained 7 unmarked tablets and the purity of these tablets was 4%. The ecstasy sample weighed 44.22 grams and its purity was 94.63%.

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

(7) Data refer to England and Wales and Scottish Police Service Authority.
