I used to smoke 3.5 packs a day and vaped to ween off the nicotine with lower and lower nicotine content before I quit. I've learned that:

Smoking can damage blood vessels--making them thicken and narrow--leading to chest pain. Perhaps an MRI or CT scan of your chest?

Nicotine can narrow arteries-- it depends how long ago your scan was...they could have missed it.

Smoking also irritates the lungs. Might want a CT scan on them. The lungs don't directly cause chest pain, as lungs don't have pain fibers, but it's worth checking out. Especially if you cough or wheeze at all. Lung irritation can be a sign of respiratory irritation when DOES cause chest pain


Some smokers and vapers experience angina from smoking. Just simply put, chest pain. Your chest just hurts. They may not find anything on the scan if it's angina.

You may not feel anxious, but if you have chest pain and your chest feels tight, that is a sign you are anxious, even if you don't feel the nervousness. A lot of people with panic attacks think they're having heart attacks. I have panic disorder and the cigarettes gave me certain panic attack symptoms.


Nicotine causes a lot. It's a stimulant like caffeine. Just because your heart monitor didn't pick it up on that specific time, doesn't mean there isn't a problem now. Depending on timing. It's kinda common for smokers to develop arrhythmia-- including Atrial Fibrillation, Tachycardia and things like that. Maybe an EKG if the pain gets too bad? To be sure?

And, of course, smoking and vaping can cause lower oxygen levels, which hurts the chest.

I'd have them check your oxygen saturation and such.

If you don't smoke regularly-- or take long enough breaks between smoking sessions, it can cause the beginning of nicotine withdrawal. Nicotine withdrawal causes chest pains and tightness too. Depending on how long you've smoked, it can hit sooner than later.


When you quit or take a hiatus... The nicotine level in the blood drops to zero in 24 hours and the carbon monoxide levels drop a few days later. I add this because nicotine leaves the blood rather quickly, so imagine how fast it starts.


I hope you're okay and the doc can figure out what's wrong for sure. Get a deeper look with diagnostic imaging, EKG for the heart and oxygen saturation check? Hope the chest pain gets handled soon!
