Disclaimer

How the journal works, where its material comes from and what it can support.

Editorial information

Articles provide documentation and general context. They do not provide medical advice, legal advice, product authentication or individualized recommendations.

Nicotine and age restrictions

Nicotine is addictive and e-cigarettes are not risk-free. This publication is intended for adults of legal age. A website age notice is not identity verification.

Regional differences

Product configurations and legal requirements vary by jurisdiction. A source page does not establish that a product is authorized for sale or use in a particular location.

External references

Source links provide attribution. They do not imply that the source endorses this publication or every statement on the site.

A NOTE FROM
THE EDITOR’S TABLE
ON METHOD

Read slowly.
Keep the context close.

A specification is a statement with a history. Before drawing a conclusion, we ask where it came from and exactly which model it describes.

Our present model notes examine public documentation. They do not substitute for physical testing. A manufacturer image can help with identification; a performance claim calls for a different kind of evidence.
