When you start choking while smoking weed, does that mean the marijuana smoke got in your lungs?

Not necessarily: We have reflexes built into our airways, before you get to the air sacs of the lungs, that cause coughing to get rid of large or irritant particles. Excessive coughing can lead to a choking sensation, and actually may result in vomiting. Anything we smoke gets into the body through the air sacs of the lungs, otherwise we would not have any effect from them, whether it is thc, nicotine or cocaine. ...Read more

What happens if you have emphysema, can you still use nicotine inhalers or does this still damage your lungs?

What happens if you have emphysema, can you still use nicotine inhalers or does this still damage your lungs?

No: although you may have more trouble with cough after using the inhaler. It is NOT nicotine that causes damage to the lungs, it is the other substances in tobacco smoke - "tars" are organic compunds produced by tobacco combustion, plus things like carbon monoxide, formaldehyde and many other additives, flavorings, preservatives etc. I would recommend the nicotine lozenges instead to avoid cough. ...Read more

While e-cigs may be somewhat safer, we really don't know their long-term effects, or what the oils, flavorings, additives and propylene glycol actually does to our body.Try stopping. ...Read more

Lung (Definition)

Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs.

At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more
