There is not enough information to say if vaping is safer. Valkyrie can verify that MDs use "Pack Years" to assess possible damage from cigarette smoke. If you smoke a pack of cigs a day for ten years you have a 10 year pack history. 2 packs daily for 10 years you have a 20 year pack history. There is not a way to measure vaping risks in the same way. So, one day we may see an "E-Cig Year" standard but we don't now. It may be decades before we see the damage. I would answer the poll questions if there was an option for "I don't know." separate from the "I don't care."
