Prema podacima trgovina narkoticima predstavlja zabrinjavajući fenomen što se povezuje s relativno visokim stupnjem njihove prisutnosti u kosovskom društvu. Istraživanje osvjetljava činjenicu da je Kosovo važna karika za međunarodnu trgovinu drogom. Sve to, zbog zemljopisnog položaja zemlje, zbog činjenice da na Kosovu ima preko 25.000 registriranih korisnika droga, ali isto tako i zbog činjenice da je u posljednja dva desetljeća prisutan trend kontinuiranog rasta uzgoja droga. Kaznena djela trgovine narkoticima pokazuju brojne individualne, obiteljske i socijalne posljedice. Taj fenomen također šteti slici Kosova u međunarodnim okvirima. Kosovo se suočava s brojnim izazovima i problemima u borbi protiv kriminala, posebno s onima koji se odnose na narkotike. U ovom su radu naznačene aktivnosti kosovskih sudova u borbi protiv kaznenih djela trgovine opojnim drogama; također se predlažu mjere promicanja učinkovitosti sudova u borbi protiv pojave.
