Abstract
A rolling paper is formed according to a modified conventional paper-making process. The end product is infused with cannabinoids from an oil extract from the cannabis plant. Since paper-making is highly water intensive and the cannabinoid containing cannabis extract is an oil that is ordinarily immiscible in the water, an emulsifier is used to allow the cannabinoids to evenly disperse in the making of the paper. The addition of the cannabinoids and the emulsifier is done prior to the drying of the paper. Preferably, the emulsifier and cannabinoids are added during the sizing step of the paper-making. Preferably the emulsifier is a starch-like carbohydrate, a modified starch, more preferably hydroxy-propyl-methyl-cellulose. The cannabinoid containing cannabis extract can be added at the pulping, web-forming step and/or preferably at the sizing step of paper-making.
