The Heaviness of Smoking Index (HSI) includes how many questions and what is its score range?

The Heaviness of Smoking Index is a tool designed to assess the intensity of tobacco consumption among smokers. It includes two specific questions that focus on the number of cigarettes smoked daily and the time to the first cigarette after waking. This simplicity allows for an efficient assessment of smoking behavior.

The score range for the Heaviness of Smoking Index is from 0 to 6, which corresponds directly to the responses given to the two questions. This scoring system provides a quick and effective way to categorize smokers based on their level of nicotine dependence. By utilizing just these two questions, the HSI can efficiently identify varying levels of heaviness, which is crucial for tailoring cessation strategies and interventions.
