Cooking temperatures that protect THC (and which ones destroy it)
THC is not as fragile as the internet suggests, but it does have a ceiling. Knowing where heat helps (decarbing), where it is neutral (most baking), and where it hurts (frying, broiling, long high heat) is what keeps the dose you calculated in the food you serve.
At what temperature does THC degrade?
THC begins converting to CBN and breaking down meaningfully above roughly 175 C (about 350 F), with losses accelerating as temperature and time climb. Below that, it is remarkably sturdy — which is why a standard bake is safer than it sounds. The oven may say 350 F, but the inside of a brownie stays near water's boiling point, around 100 C, until it is nearly done. The batter insulates the infusion.
The real danger zones are direct, dry heat: frying in infused oil, broiling, roasting infused foods uncovered at high heat, or holding an infusion at a hard simmer for hours. Surface temperatures there blow past the ceiling and take potency with them.
What are safe temperatures for common methods?
Decarbing: around 115 C (240 F) for 40 minutes — hot enough to activate, cool enough to spare terpenes. Infusing: 70 to 90 C (160 to 200 F), never a rolling boil; a slow cooker on low or a gentle water bath is ideal. Baking: standard temperatures up to 350 F are fine for batters and doughs. Stovetop: add infused oil to sauces at the end over low heat rather than sautéing in it from the start.
Where do home cooks actually lose potency?
Mostly not in the oven. The big losses hide earlier in the chain: skipping or under-doing the decarb, infusions that never got hot enough or long enough to transfer THC into the fat, and generous straining losses left behind in the plant material. If a batch came out weak, audit decarb and infusion before blaming the bake — and run the numbers through a calculator so the target was real to begin with.
Frequently asked questions
Can you bake edibles at 350 F?
Yes. The interior of a batter stays near 100 C until nearly done, well below THC's degradation range, so standard baking preserves potency well.
Can you fry with cannabis oil?
Avoid it. Pan and fryer surface temperatures far exceed THC's ceiling, and much of the potency will burn off — finish dishes with infused oil instead.
Does microwaving destroy THC?
Brief reheating of a finished edible is fine; the food's own moisture keeps temperatures modest. Just avoid long, high-power blasts.
