Vaping is heating a substance below the point of combustion, turning the oils/moisture in said substance to vapor. Oils (oleoresins) and water have a different boiling point than each other, both however boil and become vapor at much lower temperature than needed for combustion (smoking). This vapor (depending on what you choose to vape) has a different effect on your body than smoke. As a reference for comparison, the cherry on a lit cigarette burns at nearly 800 degrees Fahrenheit, this extremely high temp offgasses more than oleoresin vapor. At the extreme temperature found in combusting plant matter you will get heavy metals, and toxic chemical compounds in your smoke. The smoke being a toxic soup of poisons once in your lungs burns and destroys the cilia (small hair lke growths that aid in the transport of oxygen to your blood). The resulting wounds do not heal and as such may eventually become cancerous. Vapor from naturally occurring oleoresins (from my own first hand experience this applies to cannabis) irritate the lungs by temporarily disrupting the production of mucous. The average human body creates 1 liter of mucous every 24 hours. No one in this thread seems to know jack shit about the subject. If you are going to be for or against anything, do your own research before you blindly spout someone elses bullshit (not that you did). This is a good lesson for anyone whos too lazy to read. Ive compiled my information from books, doctors, and studies by reputable labs/colleges. On a side note, I have also had a redicculous ammount of scans done on my lungs recently at great expense (after over a decade of chain vaping) and there wasnt a single spot or any damage found. The scans were done in response to intense chest pain cause by 4 blood clots that hit my lung after a surgery. The clots were not caused by vaping but the 2 genetic platelet disorders I have. Lucky for me we found out before I died of a stroke before I turn 50, but that is another topic all together. This topic is about smoking vs vaping. This is the difference.

Jesus bunson you're too smart for offtopic
