The embodiments herein provide a filter for cigarette comprising graphene nano-composite based material enclosed in a casing. The filter is reusable and is plugged to any cigarette, or tobacco smoking products. The filter is a stand-alone product or manufactured integrally with each individual cigarette. The filter provides a safe smoking option to tobacco smokers without changing their smoking habits by reducing the tar content and other toxic chemicals in the inhaled smoke. The graphene based nanocomposite filter adsorbs the toxic agents from the smoke (of cigarette, beedi, hookah etc). The filter is fabricated by treating ceramic particles and coating them with carbon particles. The carbon particles are carbonized. The ceramic particles coated with carbon are segregated based on shape and size and treated chemically to convert carbon into graphene under inert conditions. The graphene coated particles are chemically functionalized for improved filtration.
