  Production of J/$\psi$ from nucleus-nucleus reactions depends sensitively on
the dissociation cross section with light hadrons. Effective lagrangian methods
are used to describe the hadronic degrees of freedom, including strangeness and
charm. Cross sections with pions, rho mesons, kaons and nucleons having
magnitudes 4--8 mb are found, and with steep thresholds. This, folded with
thermal momentum distributions for the scattering partners, suggests a mean
dissociation lifetime $\simeq$ 20 fm/c. Therefore, the ``abnormal'' J/$\psi$
suppression seen in recent Pb+Pb experiments seems to owe to expected hadron
kinetics.
