A nug run is a term used for a batch of cannabis concentrates that were produced exclusively with cured nuggets instead of trim or shake, which is more common. Making concentrates with buds or nugs tends to be more expensive as a higher grade of cannabis is used. Nug runs start with a higher concentration of terpenes and cannabinoids, producing a flavorful, trichome-rich, potent concentrate that many concentrate connoisseurs prefer over trim runs.
