A method of fabricating a porous carbon composition, the method comprising subjecting a precursor composition to a thermal annealing step followed by a carbonization step, the precursor composition comprising: (i) a templating component comprised of a block copolymer and (ii) a lignin component, wherein said carbonization step comprises heating the precursor composition at a carbonizing temperature for sufficient time to convert the precursor composition to a carbon material comprising a carbon structure in which is included mesopores having a diameter within a range of 2 to 50 nm, wherein said porous carbon composition possesses a mesopore volume of at least 50% with respect to a total of mesopore and micropore volumes. Also described are the resulting mesoporous carbon composition, a composite of the mesoporous carbon material and at least one pharmaceutical agent, and the administration of the carbon-pharmaceutical dosage form to a subject.
