Smelling cigarette smoke when no source is present is known as a phantom smell or phantosmia, and it can be a physical symptom of stress and anxiety.
An olfactory hallucination, known as phantosmia, makes you detect smells that aren't in your environment. The odors you notice in phantosmia are different from person to person and may be foul or pleasant. You may notice the smells in one or both nostrils.
Although lots of people think smelling something burning is a sign of a stroke, there's no solid evidence this is true. The idea of smelling phantom burning toast may be kind of amusing — but strokes are serious. They affect approximately 795,000 Americans each year — and around 137,000 of those people die as a result.
Phantosmia is usually temporary and should go away in a few weeks. But your symptoms may linger if a neurological issue is the cause. You should see a healthcare provider if phantom smells last for more than a few weeks.
Odors are interpreted in the olfactory area of the brain. Researchers suggest that a “miswiring” of the brain causes phantom smells in people with anxiety. Phantosmia may occur due to problems in the nose or olfactory receptors.
“Olfactory hallucination could be a sign of a temporal lobe tumor,” Grimm says. “It could manifest as part of a seizure.” Smelling smoke can also be a sign of other serious conditions, like stroke or Parkinson's disease.
There is also documented evidence of olfactory hallucinations for B12 deficient patients, i.e., smelling smells (usually unpleasant) that aren't actually there (medically called phantosmia).
Cigarette smoke odour removal is one of the toughest removal jobs because the smoke finds a way not only to embed in furniture but in walls as well. The smoke penetrates odour absorbent objects such as couches, carpets, upholstery, and clothes.
Causes of phantom smells can include problems with the nose, brain, or nervous system. It's important to note that phantosmia can also be caused by psychological factors, such as stress, anxiety, and obsessive-compulsive disorder (OCD)—though these cases are less common.
Other signs and symptoms may include:
If you have ruled out thirdhand smoke as the culprit, electrical faults may be the cause. When insulation on wiring gets too hot, it can emit an acrid smell that some people mistake for cigarette odour.
There is no evidence to suggest that smelling burnt toast may indicate a heart attack or a stroke, although people have anecdotally linked the conditions to the phantom odor. Phantosmia, which involves smelling phantom smells such as burnt toast, may indicate an underlying medical condition.
If the smell of smoke occurs suddenly and continues for less than a few minutes, the site of origin is likely the smell region of the inner temporal lobe of the brain, called the uncus. The source could be an abnormal electrical discharge or "firing" in the brain (a seizure).
Certain classes of prescription medications including chemotherapeutic agents, anti-hypertensive agents, antibiotics, thyroid medications, and antidepressants are understood to affect smell sensitivity (Hummel et al., 2017; Malaty & Malaty, 2013; Schiffman, 1983).
Nonenal® (also known as 2-Nonenal) is a naturally occurring compound responsible for the distinct odor associated with aging. It typically appears after age 40, becoming more noticeable in both men and women.
Orris. Distilled from the root of the bearded iris flower, orris is one of the rarest perfume ingredients in the world. Despite its high price, which in some cases have cost more than gold, the orris's scent has been sought out by people across the world.
You may be experiencing phantosmia, or olfactory hallucinations, a condition that causes you to detect smells that aren't actually present. For most people, olfactory hallucinations bring up unpleasant smells like burning rubber, garbage, chemicals, and cigarette smoke—not exactly things you want to get a whiff of.

But before we jump to any conclusions, let's clear something up—in general, falsely believing that you're smelling something burning is a common misconception about typical stroke onset, according to Salman Azhar, M.D., director of the stroke program at Lenox Hill Hospital in New York City.
10 Medical Symptoms You Should Never Ignore
Most people with phantosmia report it as an intermittent smell of something burnt, foul or unpleasant. Cigarette smoke and petrol are common but olfactory experiences can be varied. Sometimes it can be persistent.
