A cannabis tincture, often called Green Dragon, is a concentrated alcohol-based extract that captures cannabinoids in a liquid you can dose by the drop. Tinctures are prized for their versatility: a few drops under the tongue act relatively quickly, and the same liquid can be stirred into drinks, food, or recipes. Because high-proof alcohol pulls cannabinoids efficiently from the plant, a well-made tincture is potent, so understanding how to make it and how to dose it carefully are equally important. This guide covers the process from decarbing through storage.
Decarbing First
Like every cannabis preparation, a tincture begins with decarboxylation. Decarbing matters because raw flower is full of inactive THCA that only becomes intoxicating THC when heated; an undecarbed tincture will be weak and disappointing. Break your flower into small pieces, spread it on a parchment-lined tray, and bake it in a low oven, roughly 220 to 245 degrees Fahrenheit, for about 30 to 45 minutes until it turns light golden-brown and smells toasty. Be careful not to scorch it, since excessive heat destroys potency.
Let the decarbed flower cool before moving on. Skipping or shortcutting this step is the single most common reason homemade tinctures underperform, so give it the attention it deserves. Some people decarb a larger amount at once and store it for future infusions, which is fine as long as it is kept in a sealed, labeled container away from light and out of reach of children and pets.
Extracting With Alcohol
The classic Green Dragon method uses high-proof, food-safe drinking alcohol such as a neutral grain spirit, which dissolves cannabinoids effectively. Place your decarbed flower in a clean glass jar and pour in enough alcohol to fully submerge it. From here there are two common approaches. The fast method involves gentle warmth and shorter soaking, while the traditional cold method involves sealing the jar and letting it steep for days or weeks in a cool, dark place, shaking it periodically to encourage extraction.
Alcohol and heat are a dangerous combination, so never heat alcohol over an open flame; if you apply any warmth, do it gently and away from sparks, in a well-ventilated space. After steeping, strain the liquid through cheesecloth or a fine filter into a clean container, pressing the plant material to recover the absorbed liquid. The result is a deeply colored, concentrated tincture. Transferring it into amber glass dropper bottles makes it easy to dose and protects it from light.
Dosing, Use, and Storage
Tinctures can be used in two main ways. Held under the tongue for a minute or so before swallowing, some of the cannabinoids absorb through the tissues of the mouth, which tends to act faster than a swallowed edible. Swallowed outright or mixed into food and drink, a tincture behaves like any other edible, taking 30 minutes to 2 hours to kick in. Because homemade potency is hard to predict, start with just a drop or two and wait at least 1 to 2 hours before taking more.
Treat tinctures with respect, since their concentrated nature makes it easy to take too much. Always start low, go slow, and keep careful track of how many drops you have taken. Store the tincture in a tightly sealed, clearly labeled amber bottle in a cool, dark place, well away from children and pets, and be especially mindful that it contains alcohol. Effects vary between individuals, and this is general information, not medical advice; consult a professional if you have health concerns or take medications.
Frequently Asked Questions
What kind of alcohol should I use for a tincture? Use high-proof, food-safe drinking alcohol such as a neutral grain spirit, since higher proof extracts cannabinoids more efficiently. Never use rubbing alcohol or any non-consumable solvent. Food-safe alcohol is essential because you will be ingesting the finished tincture.
How is taking a tincture under the tongue different from swallowing it? Held under the tongue, some cannabinoids absorb through the mouth's tissues and effects may begin faster. Swallowed or mixed into food, the tincture acts like a standard edible with a 30-minute to 2-hour onset. Either way, start with just a drop or two and wait before taking more.
Is heating alcohol during this process dangerous? Yes, alcohol is flammable, so never heat it over an open flame or near sparks. If a recipe calls for gentle warmth, apply it indirectly in a well-ventilated area. Many people avoid heat entirely and use the cold steeping method to extract the tincture safely.
