The present invention relates generally to compositions comprising polyelectrolytes complexes (PECs) of anionic and cationic biopolymers capable of forming barriers on fiber based materials. Also disclosed is a fibre based material with a barrier coating against oil and water, wherein the material is provided with a barrier from at least two layers formed from at least one composition comprising a polyelectrolyte complex (PEC) of a cationic biopolymer and an anionic biopolymer, The two layers result in improvements in both oil resistance and water resistance compared to the same material provided with a single layer of said at least one composition.

A gum of vegetable origin for rolling cigarette paper including a solids content, includes a mixture of cannabinoids and edible oil, the edible oil being present in the mixture in a proportion p such that 0%≤p≤80% by weight of the compound. Since cannabinoids are soluble only in oil and the gum is intended to be brought to the mouth because it should be reactivatable by licking once coated, smoked and swallowed, oil is edible.
