Trace the public sentence, not the sender's private conversation
NIH advises checking the original source of social posts, even those sent by friends, and noticing the information's date.
Ask for a public link, or search a distinctive public phrase and the visible publisher name. Open the publisher's own page rather than another repost. Compare nearby wording, who the statement concerns and the original date. Similar fonts or a familiar logo cannot complete this comparison. If no original is found, leave the claim unverified; that alone does not prove the image was fabricated.
Fictional crop: doubled attendance becomes doubled success
Everything in this exercise is invented, with no real service or report. A cropped image shows ‘attendance doubled’. The forwarded caption adds ‘this group doubles quit-smoking success’. The source, when recovered, is a report from an earlier year: 10 people attended one discussion session and 20 attended another. It says nothing about smoking status after either session.
The attendance count doubled, but there is no measured quit-success outcome to double. The screenshot may reproduce its visible sentence accurately while the new caption changes its meaning. This reading does not establish why attendance changed or whether the group affects quitting. Do not infer that the person who forwarded it intended to mislead.
The uncropped page also contains an old event registration invitation. Its historical existence does not show that registration is open now, that the same group still runs or that it accepts people in your area. Check the provider's current public service page before presenting it as an available resource.
Replace the added claim, or stop at unverified
For the invented case, a useful reply is: ‘The original report compares attendance of 10 and 20 at two sessions. It does not report a quit-success rate; the registration invitation is old and current access remains unchecked.’ For a real message, supply the actual public link and source date so the reader can check the context themselves.
If the original cannot be recovered, say ‘I have only the screenshot and cannot verify the source or context’. Do not send it on as a health recommendation with a question mark, and do not invent a stronger opposing claim. An old date is a reason to check relevance, not proof that every statement is false.
Leave private details out of the search
Search the public wording rather than uploading a full chat image to a third-party service. Names, avatars, account details, phone numbers and someone else's smoking history are not needed to locate an event report. Ask for the public source instead of more private screenshots.
For your own support or treatment question, use current qualified local services and discuss it with a professional. A forwarded picture does not assess your situation or instruct you to alter prescribed care. This site does not receive your screenshot or message.
What to keep in mind
Common questions
Is a screenshot always unreliable?
No. It can be a useful clue and may reproduce words accurately. The missing surrounding text, date or current status still needs checking before using it to support a health claim.
