Which question is relevant to assessing smoking habits in a patient's social history?

The question about smoking habits that asks "Do you smoke?" is directly relevant to assessing a patient's social history because it specifically addresses the patient's tobacco use. Understanding a patient's smoking habits is essential for evaluating their overall health, risk factors for various diseases, and potential impact on treatment plans. This information helps health professionals identify risks for conditions such as cardiovascular disease, respiratory issues, and certain cancers.

The other questions, while important in their own contexts, do not pertain specifically to smoking habits. Asking about a family history of stroke provides insight into genetic risks associated with cerebrovascular diseases but does not address personal lifestyle choices. Inquiring about alcohol consumption is relevant for understanding other aspects of a patient's lifestyle, yet it does not focus on tobacco use. Finally, questions regarding allergies deal with sensitivities to substances rather than habits that affect health outcomes related to smoking. Thus, the question specifically addressing smoking is the most pertinent for evaluating the patient's social history.
