Nug
A single dried cannabis flower, colloquially called a nugget or nug.
Nug is slang for a single dried cannabis flower. The term has no official regulatory meaning—labs call it 'flower' or 'inflorescence.' Visually dense, frosty, colorful nugs look impressive, but appearance tells you almost nothing about THC content or effects. A lab test is the only way to know what you're actually getting.
Definition
A nug is a single dried and cured cannabis inflorescence—the flowering structure of a female Cannabis plant, harvested and prepared for consumption. The cannabinoid- and terpene-rich resin glands (trichomes) are concentrated on the surface of these flowers [1][2].
The word is shortened from 'nugget' and entered cannabis vernacular in late-20th-century American English. It has no formal definition in any pharmacopoeia or regulatory document; dispensaries and analytical labs typically use 'flower' or 'inflorescence' instead [3].
What a nug is botanically
A nug is a cluster of small flowers (florets), bracts, and sugar leaves bound together along a stem. Most of the cannabinoids—including THC and CBD—are produced in glandular trichomes concentrated on the bracts [1][2]. Curing reduces moisture content to roughly 10–15%, which stabilizes the flower for storage and consumption [4].
What 'nug quality' actually tells you
Common folklore says dense, frosty, colorful nugs are stronger. In reality:
- Density is shaped by genetics and growing conditions, not necessarily potency Weak / limited. Some high-THC cultivars produce naturally fluffy flower.
- Visible trichomes do not reliably predict cannabinoid content, and you cannot accurately estimate a THC percentage by looking at a nug Anecdote.
- Color (purple, orange hairs, etc.) is largely driven by genetics and temperature, not potency Weak / limited.
The only reliable way to know a nug's chemistry—THC, CBD, and terpene content—is a certificate of analysis from an accredited laboratory [3].
