The US Core Smoking Status Observation Profile inherits from the FHIR [Observation](https://hl7.org/fhir/R4/observation.html) resource; refer to it for scope and usage definitions. This profile meets the requirements of the U.S. Core Data for Interoperability (USCDI) *Smoking Status* Data Element. This profile sets minimum expectations for the Observation resource to record, search, and fetch smoking status data associated with a patient. It specifies which core elements, extensions, vocabularies, and value sets **SHALL** be present in the resource and constrains how the elements are used. Providing the floor for standards development for specific use cases promotes interoperability and adoption.
