Questione giuridica chiave
Whether the cantonal court’s factual findings on cocaine quantities and purity were arbitrary or violated the presumption of innocence.
Decisione estratta
The cantonal assessment of the evidence was not manifestly unsustainable; the presumption-of-innocence argument had no independent scope.
Motivazione estratta
The accused and drug users spoke in grams, had no reason to inflate quantities, and the expert report did not make the court’s reliance on the mean purity value untenable.
