Nug is short for nugget and refers to a high-quality, dense bud of cannabis. A nug typically indicates premium weed with a compact structure and a rich aroma. The term became popular in the 1990s as the quality of cannabis flower became a more important aspect of cannabis culture. Today, dispensaries often advertise "nugs" as a sign of top-shelf product, and cannabis enthusiasts take pride in sharing photos of their nugs on social media
