A joint and a blunt are both types of marijuana cigarettes, but they are different in several ways. Generally, a joint is smaller and thinner than a blunt. A joint is usually rolled with a thin paper that is made from either wood pulp or hemp, while a blunt is made with thicker, tobacco-leaf paper or cigar wrappers. The size and type of paper used to roll them significantly affects the flavor of the smoke.
Joints typically contain about 0.5–1 gram of marijuana, while blunts can contain up to 3.5 grams. Blunts are also packed more tightly than joints, so they burn more slowly and last longer. Additionally, because of the tobacco-leaf paper, blunts have a stronger flavor than joints.
