Making edibles at home is one of the most rewarding things you can do with homegrown cannabis. You control the dosage, the ingredients, and the quality of the flower that goes into them. But the process requires understanding a few key steps that many beginners skip, which leads to either edibles that do nothing or edibles that hit way too hard.
Get these fundamentals right and you will consistently produce edibles that are enjoyable, predictable, and safe.
Decarboxylation: The Step You Cannot Skip
Raw cannabis does not get you high.
The THC in fresh flower exists as THCA (tetrahydrocannabinolic acid), which is not psychoactive. Heating THCA converts it to THC through a process called decarboxylation. When you smoke or vaporize cannabis, decarboxylation happens instantly from the heat. When making edibles, you need to do this step separately before infusing.
To decarboxylate, break your cannabis into small pieces (do not grind it to powder, just break it into pea-sized chunks) and spread it evenly on a parchment-lined baking sheet.
Bake at 240 degrees Fahrenheit for 40 minutes. The flower will darken slightly from green to a brownish-green and will smell strongly herbal.
Lower temperature for longer time preserves more terpenes and avoids burning off THC. Going above 300 degrees or leaving it in too long will degrade the THC and give you sedative effects from CBN (a degradation product) rather than the desired THC effects.
Choosing Your Infusion Base
THC is fat-soluble, meaning it dissolves in fats and oils but not in water.
This is why edibles are made with butter, coconut oil, olive oil, or other fats rather than water-based liquids.
Butter (Cannabutter) is the classic choice. It works in baked goods, sauces, and anywhere you would use regular butter. The flavor of cannabis comes through noticeably in cannabutter, which some people enjoy and others mask with strong-flavored recipes like brownies or chocolate.
Coconut oil is the most efficient infusion base because it has the highest saturated fat content of any common cooking oil. Saturated fat binds more effectively with THC, which means you extract more potency per gram of flower. Coconut oil is also versatile. Use it in baking, cooking, smoothies, or fill capsules with it for precise dosing.
Olive oil works well for savory applications like pasta, salad dressings, or drizzling over food.
It has a lower saturated fat content than coconut oil, so extraction efficiency is slightly lower, but the flavor pairing with savory dishes makes it worth it for those uses.
Making Cannabutter (Stovetop Method)
You will need: 1 cup (2 sticks) of unsalted butter, 7 to 10 grams of decarboxylated cannabis, 1 cup of water, a saucepan, a thermometer, cheesecloth, and a storage container.
Melt the butter in the saucepan over low heat.
Add the water (it prevents the butter from burning and will separate out later). Add the decarboxylated cannabis. Stir gently.
Maintain the mixture at 160 to 180 degrees Fahrenheit. Do not let it boil. Simmer on low heat for 2 to 3 hours, stirring occasionally. The low temperature and long infusion time extract the most cannabinoids without degrading them.
After simmering, set a cheesecloth-lined strainer over a container and pour the mixture through.
Squeeze the cheesecloth gently to extract the liquid but do not press too hard (pressing releases chlorophyll and plant material that makes the butter taste more bitter).
Refrigerate the strained liquid for at least 4 hours. The butter will solidify on top and the water will settle to the bottom. Lift off the solid butter disc, discard the water, and you have cannabutter ready to use. Store in the refrigerator for up to two weeks or freezer for up to six months.
Making Infused Coconut Oil
The process is nearly identical to cannabutter.
Use 1 cup of coconut oil and 7 to 10 grams of decarboxylated cannabis. You can skip the water since coconut oil has a higher smoke point and is less likely to burn.
Melt the coconut oil over low heat, add the decarbed cannabis, and maintain 160 to 180 degrees Fahrenheit for 2 to 3 hours. Strain through cheesecloth into a storage container. Coconut oil solidifies at room temperature, so it is ready to use once it cools. Store at room temperature or in the refrigerator.
Dosing: The Most Important Part
This is where most homemade edible disasters happen.
People do not calculate dosage and end up with brownies that either do nothing or send someone to the moon for eight uncomfortable hours.
Here is a rough calculation method. If your flower tests at 20% THC, 1 gram contains approximately 200 mg of THC. Decarboxylation is not 100% efficient, so assume you retain about 80%, giving you roughly 160 mg per gram after decarbing.
If you use 7 grams in 1 cup of butter, your butter contains approximately 1,120 mg of THC total (7 grams times 160 mg).
If you use that cup of butter in a brownie recipe that makes 16 brownies, each brownie contains about 70 mg of THC.
For context, a standard dispensary edible dose is 5 to 10 mg. A 70 mg brownie is a very strong dose. For beginners or moderate users, you would want to use less flower in your infusion or cut the infused butter with regular butter in your recipe.
A sensible starting point for beginners is 5 mg per serving.
For occasional users, 10 to 20 mg is moderate. Experienced users may use 25 to 50 mg. Anything above 50 mg per serving is a strong dose that most people find overwhelming.
Safety Tips
Start low, go slow. Edibles take 30 minutes to 2 hours to kick in, depending on your metabolism and whether you have eaten recently. The most common mistake is eating a dose, feeling nothing after 45 minutes, eating more, and then getting hit by both doses at once two hours later.
Wait at least 2 hours before considering a second dose.
Label everything. Infused butter and oil look identical to regular butter and oil. Label your containers clearly so nobody accidentally uses them in a recipe they do not intend to medicate. If you have children in the house, store edibles in a locked or high location just like you would store any medication.
Track your batches. Write down how much flower you used, the approximate THC percentage, and how many servings the recipe makes. This lets you replicate batches that turn out well and adjust batches that are too strong or too weak.
Cook low and slow. When using cannabutter or infused oil in recipes, avoid high oven temperatures above 340 degrees Fahrenheit. THC begins to degrade noticeably above this temperature. Most brownie and cookie recipes work perfectly at 325 degrees with slightly longer bake times.
What to do if someone takes too much: Reassure them that it will pass (no one has ever fatally overdosed on cannabis). Find a calm, comfortable space. Cold water and a light snack can help. Black pepper (chewing a few peppercorns) contains beta-caryophyllene, which anecdotally helps reduce cannabis-induced anxiety. The effects will subside within 4 to 8 hours. If someone experiences severe anxiety or panic, do not hesitate to contact medical help.
Easy First Recipe: Simple Infused Brownies
Use your favorite boxed brownie mix (yes, from a box, there is no shame in it). Replace the vegetable oil or butter called for in the recipe with your infused coconut oil or cannabutter. Mix, pour, bake at 325 degrees until a toothpick comes out clean, and let cool completely before cutting.
Cut into portions based on your dosage math. If your total batch contains 500 mg and you want 10 mg servings, cut 50 pieces. If that seems small, use less flower in your next infusion so you can cut fewer, larger pieces at the same dose per serving.
Once you nail the basics of decarboxylation, infusion, and dosing, you can apply the same principles to any recipe. Cookies, gummies, pasta sauces, salad dressings, and even coffee creamer all work. The technique stays the same. The possibilities expand as far as your cooking skills take you.
