Understanding the Heaviness of Smoking Index (HSI)
What is HSI?
The Heaviness of Smoking Index (HSI) is a brief, validated questionnaire that measures nicotine dependence using just two key questions. It was developed to be a quick screening tool that correlates well with more comprehensive assessments.
Why These Two Questions?
- •Time to first cigarette: Indicates urgency of nicotine craving upon waking
- •Daily consumption: Reflects overall nicotine intake and tolerance
Clinical Significance
HSI scores correlate with withdrawal severity, quit success rates, and the need for pharmacological intervention. Higher scores suggest greater difficulty quitting and increased benefit from medical support.
Cessation Strategies by HSI Level
Low (0-2): Self-Help Approach
Behavioral support, smartphone apps, gradual reduction
Medium (3-4): Professional Support
Counseling, NRT patches/gum, group therapy
High (5-6): Medical Intervention
Prescription medications, intensive counseling, specialized programs
