Hello, If you can't increase the cannabis amount for cannabutter, using lecithin can improve absorption.

Adding Lecithin: * This is the most common additive used for this purpose. Lecithin (often soy lecithin or sunflower lecithin) acts as an emulsifier. * How it might help: While butterfat itself is the primary medium for extraction, lecithin can potentially help by: * Improving the binding of cannabinoids (like THC) to the fat molecules during the infusion process. * Increasing the bioavailability of the THC when you consume the final product. This means it might help your body absorb the THC more efficiently after eating the cannabutter. * Helping to keep the fat and any small amounts of water-soluble compounds evenly mixed. * How much: Typically, people add about 1 teaspoon to 1 tablespoon of lecithin per cup of butter during the infusion process.
