I smoke.
One cigarette after another, sometimes.
It never makes me cough.
Quite the opposite: it stops me from coughing.
This is the kind of sentence that should be illegal to write on the internet.
And yet it is true.
Not a recommendation.
Just true in the tiny, irritating way some facts are true before they are safe enough to explain.
My body has a mild autoimmune talent for comedy. Sometimes it coughs unless I smoke. Then it stops.
I do not like this arrangement. I do not present it as wisdom. I present it as reality being rude.
Smoke can mean poison.
Smoke can also mean: look here, before the fire becomes expensive.
Software is like that too.
After a production release, a little smoke is good for your health.
Because smoke is information.
The deploy can be green. The action can pass. The image can build. The pods can roll. The dashboard can smile with the calm expression of a person who has not checked the one thing that matters.
And still the product can be broken.
The endpoint returns 200 and lies. The queue accepts work and starves the wrong worker.
Green is a color.
Health is behavior.
A smoke test is a mirror, not a moral lecture.
That was the idea behind Still Mirror, too: a mirror, not shame.
A mirror does not judge. It makes denial more expensive.
That is what production needs after a release.
Ask the part you touched.
If you changed billing, smoke billing. If you changed search, smoke search. If you changed a callback, smoke the callback and the queue behind it. If you changed feature flags, do not only inspect the secret. Ask a fresh running process what it believes.
Good smoke tests are boring.
Homepage returns 200. Authenticated page loads. The important listing returns real data. The logs stay quiet for the exact error you just tried to prevent.
If you can automate it, automate it. If you cannot, write the runbook and do it by hand.
Customers are not smoke detectors.
Some failures are hidden. Fine. Reality keeps a few cards hidden. But many failures are just the thing we could have asked five minutes after deploy.
Small questions are mercy. They save the customer from discovering the obvious.
So, is smoking good for your health?
No.
Of course not.
And also, in one weird corner of one body, a cigarette can stop a cough.
That does not make smoking good. It makes truth annoying.
Useful truth often arrives as a symptom. As a smell. As a tiny contradiction.
Do not worship it. Do not ignore it. Look at it.
Smoke the release.
Ask the small question.
Let production contradict you while the deploy is still fresh in your hands.
Then breathe.
