Not a bit on cipro. no interaction. It is a stretch to say there is an interaction with odansetron. Cipro is pretty inert to people and mainly hits germs. There is a little interaction with the liver ability to metabolize drugs. It is small and unlikely to interact with marijuana much. Odansetron affects a chemical that is involved in the brain, so at least it is in the right ballpark for an interaction BUT it hits different brain chemicals than marijuana and not very much at that. In summary, no not likley to interact. Furthermore there can be other chemicals in marijuana. the biggest interaction iwth those and the drugs is that they often cause some nausea and odansetron would be helpful, not hurtful.
