Elbow is slang for a pound (lb) of cannabis: 16 oz, about 454 g. The word comes from saying the abbreviation "LB" out loud.

## In practice

Growers measure big [yields](https://genetixbay.com/knowledge/glossary/yield.md) in pounds: "a pound per light" means about 454 g dry from one fixture, a common benchmark for a well-run room with a high-output light. Commercial growers price and trade wholesale flower by the pound.

Possessing or transporting a pound without a licence is a serious offence in most places, even where personal use is legal. Check local rules.
