In this Brief Report we investigate the production of charged heavy particles via [gamma][gamma] fusion at high energy [ital pp] colliders. We revise previous claims that the [gamma][gamma] cross section is comparable to or larger than that for the corresponding Drell-Yan process at high energies. Indeed we find that the [gamma][gamma] contribution to the total production cross section at [ital pp] is far below the Drell-Yan cross section. As far as the individual elastic, semielastic, and inelastic contributions to the [gamma][gamma] process are concerned we find that they are all of the same order of magnitude.
