Question juridique clé
Whether the cantonal court violated the prohibition of reformatio in peius by reducing the prison term but adding a fine.
Solution extraite
No violation occurred; the overall sanction was not aggravated because the fine replaced punishment for drug consumption no longer punishable by imprisonment.
Motifs extraits
The appeal court reduced the custodial term and separately sanctioned conduct that remained punishable by an amende; the combined result was not harsher than the earlier judgment.
