THC oil is an excellent way to incorporate cannabis into cooking, with the convenience of a less intrusive form of consumption than smoking or vaping. Perhaps the biggest challenge of cooking with cannabis, however, is maintaining the potency of the THC when cooking. Heat, cooking time, and even storage can degrade THC levels, potentially reducing the potency of the end product. With the right techniques, you can maintain the potency of THC oil for cooking and have your infused food deliver the intended effects.
One of the biggest mistakes people make when they cook with THC oil is using too much heat, as it will kill THC. THC begins to break down at around 320°F (160°C) and is completely useless at temperatures over 365°F (185°C). Cooking THC too aggressively also converts it to CBN, a cannabinoid with more sedative.
To maintain THC levels, apply the following temperatures:
Not all methods of cooking can be used for THC oil. The way that cannabinoids are processed with heat controls how much THC is preserved when the meal is served.
1. Low and Slow Cooking – Gradual warming of THC oil at low heat for a long period allows slow infusing without loss of potency.
2. No Direct Heat – Rather than frying with THC oil, add it after cooking food or mix it with dressings, sauces, or cold foods.
3. Baking with THC Oil – When baking, employ lower oven temperatures (below 320°F) and bake for a longer period of time to avoid cannabinoid degradation.
4. Blending with High-Fat Recipes – As THC is fat-soluble, adding foods like butter, coconut oil, or full-fat dairy enhances absorption and stability.


Even when heated, if stored improperly, THC will break down over time. Light, oxygen exposure, and temperature fluctuations can impact shelf life and potency in infused oils.
By using these storage tips on your infused oil, you can promote long-term freshness and potency to your oil.
