Cooking with Cannabis

If you have the luxury of being able to obtain your medicine from a legal dispensary near you, you may have noticed the large selection of edibles that are beginning to overflow the shelves. These pre-made, pre-packaged cannabis infused treats are more accessible to patients nowadays than ever before, but unfortunately many edibles still come packed with sugar, high fructose corn syrup, and other unhealthy ingredients. While these processed food delights can be an easy way to get medicated on the go, many medical marijuana patients prefer making their own medicated snacks and infused meals — and for good reason. Join us as we explore all of the popular cannabis cooking techniques and become a master chef in no time!

How to Cook with Cannabis

One of the biggest questions people have when they first start cooking with cannabis is whether or not they need to decarboxylate their flower first. The answer is that either will work, but the process is more effective if you do decarboxylate your cannabis first. Cannabis flower contains THCA, which must be activated by heat to become THC. Decarboxylating the cannabis first can help ensure that you’re getting all the cannabinoids from your medical marijuana.

How to Decarb Cannabis

To decarboxylate your flower, put it in the oven for about 30 minutes at 245°F. Moist buds may take slightly longer, while dried out buds won’t take quite as long. After mixing your ground decarbed cannabis flower with butter or cooking oil, place it over low heat for about three hours. Ideally, the temperature should stay between 160°F and 200°F. Once complete, strain out the plant material and store your butter or oil in an airtight container and refrigerate for up to three months. Don’t forget to label your container, letting everyone in your household know it has been infused.

If you skip the decarboxylation step, you can still make cannabis butter or cannabis oil, but it will take much longer. Essentially, you’re just waiting for the decarboxylation process (converting THCA into THC) to happen while heating the cooking oil or butter. People who cook this way often leave their cannabis in the butter or cooking oil for almost an entire day, stirring often, without releasing as much THC as if they had decarbed it in the oven.

The great thing about making your own cannabis oil or butter is that it opens you up to all the different things you can do. Having a cannabis base (butter or oil) can make practically any recipe cannabis edible ready.

Here are just a few of the things you can do with cannabis butter and cannabis oil.

  • Cannabis Oil Recipes – Some baking recipes call for cannabis oil, and that appeals to many people. You can also get creative by doing things like sautéing veggies in cannabis oil, adding some to a fruit smoothie, or making an infused oil-based salad dressing.
  • Cannabis Butter Recipes – Cannabis butter is often used in classic cannabis edibles like brownies, but it can also do so much more. Experiment with other baked goods like pies, cakes, and bread. You can also use your homemade cannabis butter for a rich pasta sauce, or even stir a little bit into your coffee or tea.

Using cannabis as a medicine begins with understanding the basic science of decarboxylation, and why it is a crucial process in making edibles, tinctures and topical treatments. To get the full medicinal value out of your cannabis, it needs to be heated to a temperature that is just not possible to obtain in the human digestive system. The major downside of decarboxylating is that some of the more volatile terpenes (and other aromatics) that give the plant its signature aroma and flavor are lost during the process. Adding an equal amount of raw material to the decarboxylated materials may improve the taste and/or smell of your creations, but learning how to properly decarboxylate cannabis from the get-go will save you a lot of time, energy, money and product when cooking with cannabis.

The Decarboxylation Process

The predominant compounds found in cannabis are THCA and CBDA. THCA is the major cannabinoid in Cannabis, while CBDA predominates in fiber-type hemps. THCA and CBDA accumulate in the secretory cavity of the glandular trichomes, which largely occur in female flowers and in most aerial parts of the plants. The concentration of these compounds depends on the variety of cannabis and its growth, harvesting and storage conditions. When locked in their acidic forms, THCA and CBDA are not bioavailable to the body’s cannabinoid receptors. Occurring either naturally within the plant, or upon “decarboxylation” (heating the plant material), these acids are non-enzymatically decarboxylated into their corresponding neutral forms (THC and CBD).

THCA is non-psychoactive (meaning it does not produce mind and body altering effects). If you want to achieve the full psychoactive effects of your butters, fats, oils, sugars or alcohols, decarboxylating the plant material to convert the THCA to THC prior to infusion is essential.

Control of heating temperatures and times is critical when cooking with cannabis. Heating cannabis also converts THC to CBN. At about 70% decarboxylation, THC is converted to CBN at a faster rate than the THCA is converted to THC. Higher CBN levels will produce more sedative effects.

Studies show cannabidiol (CBD) has tremendous medical potential, especially in the treatment of seizure disorders and pediatric patients. Indications also suggest CBD lowers blood sugar, which makes it desirable for treating diabetes. Its sedative properties make it useful in the treatment of stress-related and sleep disorders. CBDA and CBD are non-psychoactive. Unlike THCA and THC, converting CBDA to CBD will not make a psychoactive product. CBD has a calming effect. This makes it ideal for treating children, the aged or patients that prefer less psychoactive effects. THC vaporizes quicker than CBD, so decarboxylating higher CBD varieties may produce higher CBD-enriched material. However, if you are not using a high CBD strain, extending the heating process may accomplish no more than burning off the THC.

There is much debate and opinion on this process and very little scientific evidence to establish the best method. The only real way to prove the safety, consistency and potency of your cannabis products is to have them lab tested.

How to Decarboxylate Cannabis

Forewarning: There will be a very strong odor of cannabis during this process.

  1. Preheat oven to 225° F / 110° C.
  2. Line an oven-safe dish (or a rimmed baking sheet) with parchment paper.
  3. Breaking up cannabis buds into smaller pieces by hand, place the material in the dish close together but not stacked on one another (the less unused space the better).
  4. When oven is pre-heated, bake for about 20 minutes to remove the moisture (depending on the freshness of the material). Watch for the plant color to get darker (a light to medium brown shade). When it is time to remove from the oven, the material should be crumbly looking.
  5. Set plant material aside and wait until it is cool enough to handle. Turn oven up to 240° F / 115° C and wait for it to preheat again.
  6. When the cannabis is cooled, lightly crumble by hand and distribute evenly over the bottom of the dish.
  7. Cover dish with aluminum foil, crimping the edges tight to seal and return to the oven. Continue baking for another 45-60 minutes for higher THC and 60-90 minutes for higher CBD.
  8. Remove from oven and allow to cool fully before removing the foil. Depending on the material you use, it may be fine enough and require no further processing. If not, you can place the material in a food processor or blender, pulsing the cannabis until it is coarsely ground. Be careful not to over grind the material, as you do not want a super fine powder.
  9. Place in an airtight container (glass preferred) and store in a cool, dry place.

    Over thinking the process. Whole buds and oil in a jar in boiling water or slightly less, for four hours the cannabis is decarbed in the jar. No grinding , use a french press coffee pot to filter and pour the oil into the recipe. Works great. Hope it helps!

    Thank you very much for all the wonderful information this will be my first time trying this and I hope it turns out for I consume a lot of edibles my lungs are too old smoke too many cigarettes.
