Opening claim text (preview).

What is claimed: 1. A bis-orotic acid salt-co-crystal of nicotine and orotic acid, characterized by an X-ray powder diffraction pattern having peaks at one or more of the following 2-theta diffraction angles: 8.8, 13.4, 17.7, 26.5, and 29.3. 2. The salt-co-crystal of claim 1 , wherein at least about 50% of the salt-co-crystal is in crystalline form. 3. A pharmaceutical product comprising the salt-co-crystal of nicotine and orotic acid of claim 1 and one or more pharmaceutically acceptable excipients. 4. The pharmaceutical product of claim 3 , in a form selected from the group consisting of a pill, tablet, lozenge, capsule, caplet, pouch, gum, inhaler, solution, and cream. 5. A method of preparing the salt-co-crystal of claim 1 , comprising combining nicotine and orotic acid to form a solid and isolating the solid. 6.
