Pre-rolled joints, also called marijuana cigarettes, are ready-to-smoke cannabis joints filled with cannabis flower and rolled within a paper wrap by cannabis dispensary professionals. Several factors determine how long your pre-roll will retain potency. Paper quality is important, with the most popular being organic hemp wrap, refined white paper, unrefined brown paper, palm leaf, or organic hemp paper. High temperatures will contribute to the breaking down of the joint’s potency, as will exposure to light and humidity. Therefore you should store your pre-rolls in a cool, dark place with ideal temperatures ranging from 60-68 degrees Fahrenheit. You can tell when a joint has gone bad by its appearance. It will look dried out or have become moldy. It will also probably not smell like a joint or taste the same as when fresh. Proper storage can help prolong pre-roll potency. Doob tubes are containers shaped for joint storage and made to keep air and sunlight out. Jars have airtight lids, but don’t protect against light. Mint and lozenge tins can work, although finding the right size can be a challenge and the joints could be pick up the smell from what was in the tin. If you store your pre-rolls sufficiently, you can probably expect them to last anywhere from between six months and one year.
