- 7-10 grams decarboxylated cannabis flower
- Cheesecloth or fine mesh strainer
- Double boiler or slow cooker
- Glass storage container with lid
- Cooking thermometer
Why Cannabis Oil Is a Kitchen Essential
Cannabis-infused oil offers several advantages over cannabutter for both cooking and direct consumption. Coconut oil, the most popular carrier for cannabis infusions, has the highest saturated fat content of common cooking oils at 82%, which makes it exceptionally efficient at binding THC. The high fat content means coconut oil can absorb more cannabinoids per volume than butter. Additionally, cannabis oil is vegan-friendly, dairy-free, shelf-stable at room temperature (coconut oil), and versatile enough for both sweet and savory recipes. MCT (medium-chain triglyceride) oil is another excellent carrier that remains liquid at room temperature, making it ideal for tincture-style dosing, adding to coffee, or filling capsules. Olive oil works well for savory applications like pasta sauces, salad dressings, and bread dipping but has a lower saturated fat content that may reduce extraction efficiency slightly. The infusion process is nearly identical to cannabutter — gentle heat over extended time allows THC to bind to fat molecules — making cannabis oil equally accessible to home cooks of all skill levels.
Step-by-Step: Double Boiler Method
The double boiler method provides the most precise temperature control for cannabis oil infusion. Fill the bottom pot with 2 to 3 inches of water and bring to a low simmer. Place your carrier oil in the top pot or in a heat-safe glass bowl that sits securely on top. Once the oil is warm (not hot), add your decarboxylated cannabis and stir gently to combine. Maintain the water at a low simmer — the steam provides indirect, gentle heat to the oil above. The ideal oil temperature is 160 to 180 degrees Fahrenheit, which you can monitor with a cooking thermometer. Stir every 20 to 30 minutes and add water to the bottom pot as needed to prevent it from boiling dry. Continue infusing for 2 to 3 hours. The double boiler method is preferred by many because it virtually eliminates the risk of overheating, since the oil temperature is limited by the steam temperature. This is especially important for beginners who may not yet have a feel for managing direct stovetop heat. The slow, gentle extraction preserves terpenes and prevents THC degradation, resulting in a higher-quality finished product.
Alternative Methods: Slow Cooker and Mason Jar
The slow cooker method is the most hands-off approach: combine oil and decarboxylated cannabis in the slow cooker, set to the lowest setting, and let it infuse for 4 to 6 hours. Most slow cookers on the low setting maintain temperatures between 170 and 200 degrees Fahrenheit, which is ideal for cannabinoid extraction. Stir every hour and check that the oil never approaches boiling. The mason jar method adds a layer of odor control: combine oil and cannabis in a sealed mason jar, place the jar on a folded kitchen towel in a pot of water, and simmer for 2 to 3 hours. The sealed jar traps aromas and prevents water contamination. Make sure to only lightly tighten the lid to allow pressure release and prevent the jar from cracking. An immersion circulator (sous vide) offers the most precise temperature control possible: seal oil and cannabis in a vacuum bag, set the circulator to 185 degrees Fahrenheit, and cook for 4 hours. This method produces the most consistent results and is increasingly popular among experienced cannabis cooks. Regardless of the method chosen, the principles remain the same: gentle heat, adequate time, and careful temperature management.
Straining, Storage, and Shelf Life
After infusing, allow the oil to cool for 10 minutes until safe to handle but still liquid. Strain through cheesecloth or a fine-mesh strainer into a clean glass container. For coconut oil, which solidifies below 76 degrees Fahrenheit, strain while warm to ensure all oil passes through the cloth. Squeeze the cheesecloth gently — cannabis plant material absorbs a surprising amount of oil, so a gentle squeeze can recover 10 to 20 percent more finished product. Unlike cannabutter, cannabis oil does not require a water separation step since no water is used in the infusion process. Storage depends on your carrier oil: coconut oil can be stored at room temperature in a cool, dark location for up to 3 months, or refrigerated for up to 6 months. Olive oil should be stored in a dark glass container and used within 2 months. MCT oil is the most shelf-stable option and can last 6 months or more at room temperature. All cannabis oils should be stored away from direct light and heat, which degrade cannabinoids over time. Label each container with the preparation date, strain, amount of cannabis used, estimated total THC, and per-teaspoon potency estimate for safe, consistent dosing.
Cooking with Cannabis Oil: Tips and Applications
Cannabis oil can replace regular oil in virtually any recipe, but a few considerations maximize results. THC begins to degrade at temperatures above 320 degrees Fahrenheit, so avoid using cannabis oil for high-heat searing or deep frying. Baking at 325 to 350 degrees Fahrenheit is generally safe since the internal temperature of baked goods rarely exceeds 200 degrees Fahrenheit even when the oven is hotter. For no-heat applications — salad dressings, smoothies, drizzling on finished dishes — cannabis oil delivers its full potency without any degradation risk. When substituting cannabis oil in recipes, start by replacing only half the oil called for with cannabis oil and use regular oil for the remainder. This reduces potency per serving while maintaining the recipe's texture and flavor. Cannabis coconut oil makes excellent capsules: warm the oil until liquid, fill empty gelatin or vegetarian capsules using a small syringe, and refrigerate to solidify. Each capsule provides a consistent, precisely measured dose that is convenient for daily use. The cannabis oil market has become a significant product category for publicly traded cannabis companies, and investors tracking the edibles sector on CannaCap can see how consumer preferences are driving product innovation across licensed producers and multi-state operators.
Frequently Asked Questions
Which oil is best for cannabis infusion?
Coconut oil is considered the best overall carrier due to its 82% saturated fat content, which maximizes cannabinoid absorption. MCT oil is best for tinctures and capsules due to its liquid state at room temperature. Olive oil is preferred for savory cooking. Avocado oil offers a neutral flavor with high smoke point for versatile cooking.
Can I make cannabis oil without decarboxylation?
Technically, the infusion process provides some decarboxylation through prolonged heat exposure. However, pre-decarboxylation ensures much more complete THCA-to-THC conversion and results in significantly more potent oil. Always decarboxylate first for maximum potency.
How long does cannabis oil last?
Coconut cannabis oil lasts 2-3 months at room temperature and up to 6 months refrigerated. Olive oil-based infusions last about 2 months. MCT oil-based infusions last up to 6 months at room temperature. All cannabis oils should be stored in dark glass containers away from heat and light.
Can I use cannabis oil topically?
Yes. Cannabis-infused coconut oil makes an excellent base for topical applications. When applied to skin, cannabinoids interact with local CB1 and CB2 receptors without producing systemic psychoactive effects. Topical cannabis oil may help with localized pain, inflammation, and skin conditions.
How do I calculate the potency of my cannabis oil?
Use this formula: (grams of cannabis x THC% x 1000 x 0.85) / number of teaspoons in your batch = mg THC per teaspoon. For example: 7g of 20% THC flower produces approximately 1190mg total THC. In 1 cup (48 tsp) of oil, that equals roughly 25mg per teaspoon.
