No, it’s not something you smoke. A neti pot is a container with a spout used to pour salt water through your nasal passage.
I have been using one recently, and now I breathe clearly through both nostrils, and I smell all sorts of things that I had missed before. It is easy to do it improperly and cause pain or lose the benefits, so I recommend this one, both for its extensive instruction manual, and its quality of construction.
