Still Relying on Self-Reported Data?
When it comes to determining smoking and alcohol consumption status, it can be tempting to simply rely on self-reported data ...

Just ask someone ifand how oftenthey
smoke or drink!
But, for a variety of reasons, this method isn't accurate. When asked, answers may be skewed because people:

  • Want to present themselves in a socially acceptable manner
  • Believe what they're saying to be true (even if it isn't)
  • Have distorted views based on recent consumption (or lack of consumption)
  • Fear their answers aren't confidential
  • Mishear or misunderstand questions
  • Honestly underestimate consumption
Smoke Signature® and Alcohol Signature™ are epigenetic tests that give you accurate pictures of consumption over time so you don't have to rely on self-reported information. Instead, you're using accurate data that quantifies usage over time.
