What is a Doink?
A doink is a premium cannabis joint rolled with a structured tip — specifically 9mm diameter or larger. Unlike casual joints, a doink is an intentional, architecturally-considered roll: tight construction, quality paper selection, and a tip that delivers a full, open draw. It's the craft beer of the cannabis world — and DoinkUniversity is where you learn to roll one right.
