Quick replies
Things readers ask us first
Brief answers here; the longer versions live on Questions, Answered.
Does anyone on the team have medical training?
No. We are writers who rely on public guidance and say plainly where our knowledge ends.
Will you tell me if my readings are normal?
We explain how to measure carefully, but what the result means for you is a question for your GP or nurse.
Are the vaping entries meant for non-smokers?
Never. They are written for adults who already smoke and want a balanced look at alternatives.
How can I flag an error?
Email us with the entry title and what looks wrong; corrections are checked and dated.
