Here's How Many Cigarettes People In The Northeast Are Breathing In A Day From Wildfire Smoke

    OK, I'm staying inside.

    The wildfire smoke in the Northeast is truly, truly wild right now.

    In some places, it literally looks like Mars.

    One tweet in particular went viral, comparing smoking cigarettes to breathing in wildfire smoke.

    New York City now has the worst air quality of any city on Earth.

    If exposed to the current air quality in NYC for 24 hours, it would be equivalent to smoking about 6 cigarettes. pic.twitter.com/EWeEnQH9ya

    The tweet said spending one full day in NYC yesterday was equivalent to smoking six cigarettes.

    A six-pack of cigarettes

    I was wondering where this information came from, and there's actually a study from Stanford that was done in 2020.

    Health Impacts of Wildfire Smoke

    So, in order to calculate a cigarette equivalent, you need to know what the AQI is.

    What's AQI? It means Air Quality Index.

    There are various levels of the index, from green (good) to maroon (hazardous).

    The index: Green (good), Yellow (Moderate), Orange (Unhealthy for Sensitive Groups), Red (Unhealthy), Purple (Very Unhealthy), Maroon (Hazardous)

    The AQI in some places of Upstate New York is over 300.

    **BREAKING the AQI has now really spiked well into the 300s at 351 at 9am and is now considered HAZARDOUS. This is insane. Please be careful and take it easy outside! pic.twitter.com/A2lDV2q78p

    Over 300 is "hazardous," signifying "emergency" conditions.

    Umm........300 AQI tomorrow morning here 😨😳 pic.twitter.com/smOo9d7Bo7

    So, now you know what AQI is, let's go back to cigarettes.

    Kari Nadeau is the director of the Sean N. Parker Center for Allergy and Asthma Research at Stanford University, and she says: "An AQI measurement of 20 is equivalent to smoking one cigarette a day."

    She says: "Communities exposed to wildfire smoke causing AQI of 150 for several days is equivalent to about seven cigarettes a day if someone were outside the whole time."

    She also says you're not immune if you're indoors. "Even if you’re indoors, you could be breathing in this poor air quality due to leakage."

    So, let's go back to that picture from Binghamton.

    At last check, the AQI was 391 in Binghamton.

    That means, according to this math, spending a full day in that specific climate condition is equivalent to smoking about 19 cigarettes.
