CMS has searched for exotic charmonium states in the data sample collected in proton-proton collisions at 7 TeV in 2011. The X(3872) state is reconstructed in the J/psi pi+ pi- decay channel and the production cross-section is computed by determining the ratio to psi(2S) production in the same decay channel. For the first time, prompt and non-prompt contributions to the X(3872) cross section are disentangled by looking at secondary vertices. Furthermore, we also report on searches for other exotic quarkonium states.
