Best Oils for Cannabis Infusion Explained

Choosing the Right Oil for Your Cannabis Infusion

The art of cannabis infusion has become a cornerstone of the modern cannabis industry. Manufacturers and home enthusiasts alike rely on specific techniques and quality carrier oils to extract the potent cannabinoids and beneficial compounds from the cannabis plant. Understanding the role of oil in this process is crucial for achieving desired results, whether for culinary creations or topical applications. Oils act as solvents, effectively drawing out and suspending THC, CBD, and other valuable elements like terpenes, making them bioavailable for consumption or external use. The choice of oil can significantly impact the flavour, potency, and overall efficacy of your infused products. Popular choices often include coconut oil, olive oil, vegetable glycerin, and MCT oil, each offering unique characteristics.

Popular Oils for Cannabis Infusion: A Closer Look

The 'best' oil for cannabis infusion is ultimately subjective and depends heavily on your intended use and personal preferences. Each oil brings its own set of advantages to the infusion process. Let's delve into some of the most favoured options:

Coconut Oil: A Versatile Favourite

Coconut oil, particularly virgin coconut oil, is highly regarded for its rich saturated fat content. This high fat content makes it exceptionally effective at binding with and absorbing cannabinoids. Its versatility is a major draw, as it can be seamlessly incorporated into both culinary dishes and topical formulations. Many appreciate coconut oil for cannabis infusions due to its subtle, sweet flavour profile and its solid consistency at room temperature, which can be advantageous for certain recipes. Furthermore, coconut oil boasts a long shelf life, often remaining stable even without refrigeration, which adds to its convenience.

Olive Oil: Flavour and Potency Preservation

Olive oil, especially extra virgin olive oil (EVOO), is another widely chosen oil for cannabis infusions. It is known for its ability to preserve the delicate flavours and potency of the cannabis plant. Olive oil's versatility extends to a wide range of culinary applications, making it an ideal carrier oil for dressings, dips, and low-heat cooking. Its distinct flavour profile can complement the cannabis, adding a layer of richness to the final product.

MCT Oil: A Highly Bioavailable Option

Medium-Chain Triglyceride (MCT) oil, often derived from coconut or palm oil, is celebrated for its rapid absorption and high bioavailability. This means the body can process the cannabinoids more quickly and efficiently. MCT oil is typically liquid at room temperature and has a neutral flavour, making it an excellent choice for those who want the cannabis flavour to be subtle or non-existent in their final product. It's particularly popular for tinctures and sublingual applications.

Vegetable Glycerin: For Water-Soluble Extracts

Vegetable glycerin is a plant-based liquid that is water-soluble. While not traditionally used for fat-soluble cannabinoid extraction in the same way as oils, it is sometimes used in specific tincture formulations or to create cannabis-infused products where a water-based solvent is preferred. It has a sweet taste and can contribute to a smooth texture.

What is Cannabis-Infused Oil?

At its core, cannabis infusion is the process of extracting the beneficial chemical compounds, such as cannabinoids and terpenes, from cannabis plant material into a solvent. In the case of cannabis-infused oil, the oil acts as the solvent. Think of it like making a cup of tea; the hot water (solvent) extracts the flavour and compounds from the tea leaves (plant material). Similarly, when cannabis is steeped in oil, the fat-soluble compounds from the cannabis dissolve into the oil. The resulting liquid is the cannabis-infused oil, often referred to as 'canna oil' or 'cannabutter' if butter is used as the solvent.

Estimating the Potency of Your Cannabis-Infused Oil

A common concern for those new to cannabis infusions is understanding the strength or potency of their final product. Edibles and tinctures can have delayed effects, leading some to mistakenly overconsume. Knowing the approximate milligram (mg) dosage of THC, CBD, or other cannabinoids per serving is crucial for a controlled and enjoyable experience. While professional lab testing is the only way to determine exact potency, a basic estimation can be made using the following steps:

Step 1: Calculate Milligrams of Cannabinoids in Your Cannabis

1. Convert grams to milligrams: Multiply the weight of your cannabis in grams by 1000. For example, 5 grams of cannabis x 1000 = 5000 mg of cannabis.
2. Determine cannabinoid percentage: Find out the THC or CBD percentage of your cannabis. If this information isn't readily available, you'll need to estimate. Let's assume your cannabis has 20% THC.
3. Calculate total cannabinoids: Multiply the total milligrams of cannabis by its cannabinoid percentage. Example: 5000 mg (cannabis) x 20% (THC) = 1000 mg of THC.

Step 2: Estimate the Infusion Rate

It's important to understand that not all cannabinoids from the cannabis plant will transfer into the oil. Factors like decarboxylation, the type of oil used, infusion temperature, and duration all play a role. A realistic infusion rate typically falls between 50% and 80%. For safety, it's often better to err on the higher end of your estimate if you're concerned about under-dosing, as you can always consume more.

Example: 1000 mg (total THC) x 80% (estimated infusion rate) = 800 mg of infused THC.

Step 3: Determine Total Milligrams Per Serving

1. Measure final oil volume: After straining, measure the total volume of your infused oil. Let's say you started with 2 cups of oil and ended up with 1.75 cups (or 1 and 3/4 cups).
2. Divide oil into portions: Determine how you will divide your infused oil for recipes. If you plan to use 1/4 cup portions, calculate how many 1/4 cups are in your total volume. 1.75 cups contains seven 1/4 cup portions.
3. Calculate cannabinoids per portion: Divide the total infused cannabinoids by the number of portions. Example: 800 mg (infused THC) ÷ 7 portions = approximately 114 mg of THC per 1/4 cup.
4. Calculate cannabinoids per serving: If your recipe uses a specific portion of oil and is divided into a certain number of servings, calculate the final dosage per serving. Example: If a recipe uses 1/4 cup (containing 114 mg THC) and is divided into 12 servings, then 114 mg ÷ 12 servings = approximately 9.5 mg of THC per serving.

Remember, individual tolerance varies. Always start with a small serving and wait a few hours to gauge the effects before consuming more.

What Kind of Oil Should I Use? Factors to Consider

The ideal oil for your cannabis infusion hinges on what you plan to create:

• Flavour Profile: Some oils have distinct flavours that can complement or overpower your recipe. Neutral oils are best for baked goods where you don't want the oil's taste to interfere. Oils with stronger flavours, like extra virgin olive oil, can be excellent for dressings or savoury dishes.
• Cooking Method: Consider the smoke point of the oil. Oils with higher smoke points are more forgiving if your infusion process involves higher temperatures.
• Dietary Needs and Health: The nutritional profile of the oil, such as its omega fatty acid ratio, might be a consideration for some users.
• Cost and Shelf Life: Practical considerations like affordability and how long the oil will remain stable are also important.

Neutral Oil Examples:

• Refined Coconut Oil (often solid)
• MCT Oil (liquid)
• Vegetable Oil
• Canola Oil
• Extra Light Olive Oil
• Grapeseed Oil

Oils with Stronger Flavours:

• Virgin Coconut Oil (distinct coconut flavour)
• Extra Virgin Olive Oils (robust flavour)
• Hemp Seed Oil

Beyond THC: Exploring Other Cannabinoids

Your cannabis infusion doesn't have to be limited to THC. The growing availability of diverse cannabis genetics means you can explore other cannabinoids like CBD (cannabidiol), CBN (cannabinol), and CBG (cannabigerol). You can choose strains with balanced cannabinoid profiles or even combine different types of flower for a unique infusion tailored to your specific needs.

Decarboxylation: Activating Your Cannabis

Decarboxylation, often shortened to 'decarbing,' is a critical step for activating the psychoactive compounds in cannabis, particularly THC. Without decarboxylation, consuming cannabis edibles or oils will not produce the desired 'high.' While time, heat, and light naturally initiate this process, applying controlled heat significantly speeds it up. Smoking cannabis inherently decarboxylates it. To make edibles psychoactive, decarboxylation is essential.

Methods of Decarboxylation:

• Oven Method: This is the most common at-home method. It involves breaking down cannabis buds and baking them at a specific temperature for a set duration.
• Water Bath: Some methods utilize a water bath to provide a gentler, more controlled heat application.
• Specialised Units: Various devices are commercially available designed specifically for decarboxylating cannabis.

General Guidelines for Decarboxylation:

The optimal temperature range for decarboxylating THC is typically between 200°F and 245°F (93°C to 118°C) for 30-40 minutes. For CBD, slightly longer exposure to heat may be beneficial.

Tips for Effective Decarboxylation:

• Spread the Herb: Distribute your cannabis evenly on a baking sheet lined with parchment paper or in a glass dish to maximize surface area exposure to heat.
• Low and Slow: A "low and slow" baking approach helps prevent overheating and preserves valuable cannabinoids and terpenes.
• Monitor Temperature: Use an oven thermometer to ensure your oven is at the correct temperature, as oven thermostats can be inaccurate.
• Gentle Agitation: Occasionally shaking or stirring the cannabis during baking can promote even decarboxylation.
• Covering: Covering your baking dish with an oven-safe lid or foil can help trap vapours, allowing them to re-condense back onto the herb, potentially enhancing cannabinoid retention and minimizing odours.
• Cooling: Allow the decarboxylated cannabis to cool completely, preferably covered, to capture any volatile compounds released during heating.
• Dryness Matters: Drier cannabis buds may require slightly less decarboxylation time.
• Freezing: Some enthusiasts find that freezing decarboxylated cannabis for about 60 minutes can make trichomes easier to detach, improving infusion efficiency.

Importantly, the heat applied during the oil infusion process itself can also contribute to further decarboxylation. Therefore, while proper initial decarboxylation is beneficial, don't overly stress about achieving absolute perfection in this first step. The key is to avoid excessive heat or prolonged exposure at any stage, as this can degrade the precious cannabinoids and terpenes.
