The Decarb Blunder: Why Most Homemade Cannabis Cookies Fail Before Entering the Oven
Determining the exact THC dosage per serving prevents accidental overconsumption. Commercial operations rely on high-performance liquid chromatography, but home bakers can estimate potency using a standard mathematical formula that accounts for typical extraction loss.
Assume an average extraction and decarb efficiency rate of roughly 70% to 75% for basic home setups:
[Weight of Flower (mg) × THC Percentage] × 0.70 (Loss Factor) = Total Yield THC (mg)
If you infuse 7 grams (7,000 mg) of cannabis testing at 18% THC into one cup of butter, your starting potential is 1,260 mg of THC. Accounting for the 70% realized yield leaves approximately 882 mg of active THC across the entire cup of butter. If your cookie batch uses half a cup of that butter (441 mg THC) and yields 24 cookies, each cookie contains roughly 18.4 mg of THC.
For individuals unaccustomed to edibles, a single 18 mg portion can cause disorientation, dry mouth, and tachycardia. Aim for a beginner-safe baseline of 2.5 to 5 mg per piece by substituting half of the infused butter with standard uninfused grocery butter.
Accounting for onset time and digestion is essential for edible overdose prevention. While inhaled cannabis enters circulation through the alveoli in seconds, oral cannabinoids require mechanical breakdown in the stomach followed by emulsification in the duodenum. Effects routinely take 45 to 90 minutes to appear, occasionally stretching to two hours depending on recent meal consumption and individual metabolic speed. Redosing within the first two hours remains the most common route to an overwhelming physical reaction.
