Moroccan security authorities seized 380 kg of cannabis in the central city of Marrakech, police said in a statement.
The banned narcotic was packaged in 15 bags and found near a highway connecting Marrakech to Casablanca, it added.
A suspect aged 46 was arrested for his alleged involvement in the possession and trafficking of drugs.
