none.
vital lung capacity is how much air remains in your lungs after you exhale
your giving your lungs a chance to absorb as much THC from the smoke as possible but really 2-3 seconds is all you need to hold any longer and your just burning your lungs
You crawl because if you breathe in too much smoke in could really hurt hurt your lungs and you could pass out.
It might depend on how much you smoke... Light, heavy..??
I started smoking when I was twelve. That was because I wanted to try something new. Not to be cool as some people think. When u smoke you don't inhale as much to get the smoke to your lungs. Exhale and no nicotine no tar and no addiction. I saw a butt on the ground and grabbed it. A bodily matches and went behind the shed. It was exhilirating. Apparently if your drunk you don't get addicted.
lungs do all your breathing for you so for example if you smoke to much you will clog your lungs so you will have to have an operation in which they cut a hole in your neck and into your lung then they 'scoop' the tar out of your lungs and your forever breath through a large hole in your neck.
You are not supposed to inhale a cigar. But even at that a small amount will enter the lungs.
If you hang around say a friend that smocks and you breath it in to much your lungs will get infect.
You get blackened lungs because of the smoke going into them. You get yellow teeth because they get stained from smoking too much and don't get them cleaned by a dentist in six months. You get bad breath from the tar in the cigarettes.
To have healthy lungs you have to eat healthy. You have to eat different vegetables and fruits. It is OK to eat fast food but not so much. The important thing is not to smoke a cigar. The waves in your lung makes it clean and healthy. The cigar smoke destroys these waves.
smoke has carbon dioxide your body can only take a certain amount of co2 we breathe in oxygen when too much carbon dioxide go into the system it cooks the lungs turning the lung black whereby you will have problems breathing
Pretty much all of them. The lungs and airways are hardest hit, as they have to deal with the actual particles in the smoke, but then as the nicotine gets picked up by the bloodstream it gets carried to every part of your body.
