What is Cannabis Butter (Cannabutter)?
Cannabis butter, commonly called cannabutter, is regular butter infused with activated THC and other cannabinoids from cannabis flower. This cannabis-infused butter serves as the base ingredient for countless cannabis edibles, from brownies and cookies to savory dishes. Unlike smoking, edibles made with cannabutter provide longer-lasting effects, making proper dosage calculations essential for a safe experience.
Why Decarboxylation is Critical for Cannabis Edibles
Before making cannabutter, you must decarboxylate (decarb) your cannabis flower. Raw cannabis contains THCA, which doesn’t produce psychoactive effects. Decarboxylation converts THCA into active THC through controlled heat application. Without proper decarboxylation, your cannabis edibles won’t deliver the desired potency.
How to Decarboxylate Cannabis for Edibles
Temperature and Time: 240°F (115°C) for 40 minutes
Step-by-Step Decarboxylation:
- Preheat your oven to 240°F (115°C)
- Break cannabis flower into small, uniform pieces
- Spread evenly on parchment-lined baking sheet
- Bake for 40 minutes, stirring halfway through
- Cannabis should appear lightly golden and crumbly when ready
Cannabis Butter Recipe: Step-by-Step Instructions
Ingredients for Cannabutter:
- 1 cup (2 sticks) unsalted butter
- 7-10 grams decarboxylated cannabis flower
- 1 cup water
- Fine mesh strainer or cheesecloth
Equipment Needed:
- Double boiler or slow cooker
- Wooden spoon
- Fine mesh strainer
- Clean container for storage
Cannabis Butter Instructions:
Step 1: Prepare Your Setup Set up a double boiler or use a slow cooker on low heat. The gentle, indirect heat prevents burning your cannabis butter while ensuring proper cannabinoid extraction.
Step 2: Combine Ingredients Add butter, water, and decarboxylated cannabis to your cooking vessel. The water prevents the butter from burning and will separate during cooling.
Step 3: Infusion Process Simmer the mixture on low heat for 2-4 hours, stirring occasionally. Maintain temperature between 160-180°F (71-82°C). Longer infusion times generally result in more potent cannabutter.
Step 4: Strain the Cannabis Butter Pour the mixture through a fine mesh strainer or cheesecloth into a clean container. Press the plant material gently to extract remaining butter, but avoid over-squeezing to prevent chlorophyll contamination.
Step 5: Separate and Store Refrigerate the strained mixture overnight. The cannabis butter will solidify on top, and water will remain below. Remove the solid cannabutter and discard the water.

Cannabis Edibles Dosage: Critical Safety Information
Proper dosage calculation is essential for safe cannabis edibles consumption. Edibles affect everyone differently, and effects can take 30 minutes to 2 hours to manifest.
Calculating Cannabis Butter Potency
Basic Dosage Formula: (Cannabis flower THC% × Weight in grams × 1000) ÷ Amount of butter = mg THC per gram of butter
Example Calculation: Using 8 grams of 20% THC cannabis in 1 cup (227g) butter: (20% × 8g × 1000) ÷ 227g = approximately 7mg THC per gram of cannabutter
Recommended Edibles Dosage Guidelines:
- Beginners: 2.5-5mg THC
- Occasional users: 5-10mg THC
- Regular users: 10-20mg THC
- Experienced users: 20mg+ THC
Important: Always start with the lowest recommended dose and wait at least 2 hours before consuming more. Cannabis edibles effects are delayed but longer-lasting than smoking.
Best Practices for Cannabis Butter Storage
Proper storage maintains cannabutter potency and prevents spoilage:
- Refrigerator: Store up to 2 weeks in airtight container
- Freezer: Freeze up to 6 months in wrapped portions
- Labeling: Always label with THC content and date made
Safety: Keep away from children and pets
Cannabis Edibles Recipes Using Cannabutter
Your homemade cannabis butter can be substituted 1:1 for regular butter in most recipes. Popular cannabis edibles include:
- Cannabis brownies and cookies
- Cannabis gummies (using cannabutter in oil-based recipes)
- Savory dishes like cannabis-infused pasta or vegetables
- Cannabis chocolate and candy
Advanced Cannabis Butter Techniques
Double Infusion Method: For extra-potent cannabutter, strain your first batch and repeat the infusion process with fresh decarboxylated cannabis using the same butter.
Lecithin Addition: Add 1 tablespoon sunflower lecithin per cup of butter to improve cannabinoid bioavailability and create more consistent cannabis edibles.
Temperature Control: Use a candy thermometer to maintain precise temperatures during infusion. Consistent heat prevents degradation of valuable cannabinoids.
Legal Considerations for Cannabis Edibles
Cannabis laws vary significantly by location. Always verify local regulations regarding:
- Cannabis possession limits
- Home cultivation rules
- Edibles manufacturing restrictions
- THC potency limits for homemade edibles
Only make cannabis butter where cannabis is legal for adult use or medical purposes.
Cannabis Butter vs. Cannabis Oil: Which is Better?
While this guide focuses on cannabis butter, cannabis oil offers some advantages:
- Cannabis oil has longer shelf life
- Cannabutter provides richer flavor for baked goods
- Both require proper decarboxylation and dosage calculations
- Choice depends on intended edibles recipes
Maximizing Cannabis Edibles Effects
To optimize your cannabis edibles experience:
- Consume with fats: Cannabinoids are fat-soluble
- Empty stomach: Faster onset, stronger effects
- Stay hydrated: Essential for comfortable experience
- Plan ahead: Effects last 4-8 hours
- Safe environment: Consume in comfortable, familiar setting
Frequently Asked Questions (FAQ)
Q: Why is my cannabis butter not potent enough?
A: Weak cannabutter typically results from inadequate decarboxylation or insufficient infusion time. Ensure you’re decarboxylating at exactly 240°F for 40 minutes, and consider extending your infusion time to 4 hours. Also verify your cannabis flower’s THC percentage and recalculate your dosage expectations.
Q: How do I fix bitter-tasting cannabis butter?
A: Bitter cannabutter usually contains too much chlorophyll from over-processing plant material. To fix this: use clarified butter, avoid over-squeezing during straining, grind cannabis coarsely rather than finely, and consider water-washing your finished butter by melting it with water, cooling, and removing the separated butter layer.
Q: Can I use trim or shake instead of flower for cannabis butter?
A: Yes, but you’ll need to use more material and adjust your dosage calculations. Trim and shake typically contain 5-15% THC compared to 15-25% in quality flower. Use 2-3 times more trim than you would flower, and test your finished product carefully to determine actual potency.
Q: My cannabis butter separated or looks curdled – is it ruined?
A: Separated cannabutter can often be saved. This happens when temperatures get too high or the mixture cools too quickly. Gently reheat the mixture while stirring constantly, or blend it with an immersion blender. If the separation is severe, strain out any curdled pieces and continue with the clarified portion.
Q: How long should I wait to feel effects from cannabis edibles?
A: Cannabis edibles effects typically begin 30 minutes to 2 hours after consumption, with peak effects at 2-4 hours. Factors affecting onset time include: your metabolism, recent food consumption, body weight, and individual tolerance. Never consume additional edibles within 2 hours of your first dose.
Q: Can I make cannabis butter without smell?
A: While you can’t eliminate the smell entirely, you can minimize it by: using a slow cooker with tight lid, decarboxylating in mason jars, running exhaust fans, using activated carbon filters, or trying cold-extraction methods like freezing cannabis in butter for several days with occasional mixing.
Q: What’s the shelf life of homemade cannabis butter?
A: Properly stored cannabutter lasts 2 weeks refrigerated or 6 months frozen. Signs of spoilage include: off smells, mold growth, color changes, or rancid taste. Always label with creation date and store in airtight containers away from light and heat.
Q: Can I use salted butter for cannabis butter?
A: While unsalted butter is preferred for better flavor control, you can use salted butter. The salt won’t affect cannabinoid extraction, but it may impact the taste of your final edibles. Reduce added salt in recipes when using salted cannabutter.
Q: Why did my cannabis turn brown during decarboxylation?
A: Light browning is normal and indicates proper decarboxylation. However, dark brown or black cannabis means you’ve overheated it, potentially destroying valuable cannabinoids and terpenes. Stick to 240°F for 40 minutes maximum, and consider lowering temperature to 220°F for 45 minutes if your oven runs hot.
Q: Can I reuse cannabis material after making butter?
A: The plant material after straining (called “pulp”) still contains some cannabinoids but significantly less than fresh material. You can compost it, use it for topicals, or save it for a weaker second extraction. Don’t consume it directly as it’s difficult to digest and may cause stomach upset.
Q: How do I calculate dosage for cannabis edibles recipes?
A: First determine your cannabutter’s potency per gram, then calculate based on recipe usage. Example: If your cannabutter has 10mg THC per gram and your brownie recipe uses 100g cannabutter making 20 brownies, each brownie contains approximately 50mg THC (1000mg total ÷ 20 brownies). Always start with small test batches.
Q: What temperature should I maintain during cannabis butter infusion?
A: Maintain 160-180°F (71-82°C) during infusion. Use a candy thermometer for accuracy. Temperatures below 160°F won’t extract efficiently, while temperatures above 200°F can degrade THC into less desirable compounds. Consistent, gentle heat is key for quality cannabutter.
