Unless you’ve been “living under a rock," as the popular saying goes, you’ve likely heard about, seen an ad for, watched someone else use, or even tried e-cigarettes.  New “nicotine delivery devices,"  as they’re categorized, are entering the marketplace every day.
You may have heard that e-cigarettes are less dangerous than smoking tobacco products – or that they’re even being promoted as smoking cessation aids.
These claims, though, are not supported by evidence. Instead, there are a few concerning facts and many, many unanswered questions.
Other Reliable Sources
Other science-vetted points:
  • There’s no way for you to know how much nicotine is entering your body from an e-cigarette, in addition to the other unknown substances.
  • There are several FDA-approved (and insurance-covered) quit aids that have been proven safe.

What We Do Know
The science-based resource  here at NIH – Smokefree.gov – lists these facts about e-cigarettes:
  •   E-cigs contain nicotine.
  •   E-cigs aren’t regulated.
  •   E-cigs haven’t been shown to be effective. 
In other words:
  • They still cause and maintain nicotine        
  • Users inhale an unknown mix of otherchemicals, often from outside theU.S., where many cigarettes are manufactured. 
  • They have not been proven to be effective, and are definitely not risk-free, for tobacco cessation use.
When You're at Work​
The NIH Tobacco-Free policy prohibits the use of e-cigarettes.
