Combustion and vaporization have a separate heating temperature. When something is heated at a very high temperature, combustion happens. Whereas in vaporization the substance is not heated at much temperature.
In the language of chemistry science, in the process of combustion, you burn the substance that blend with the oxygen that creates heat and light. It produces carbon monoxide when is injurious, has no colour and unscented gas. The combustion process can be incomplete or complete.
Cooking, lighting a fire, smoking a cigarette are caused by combustion. A high level of combustion can cause suffocation, can make you unconscious and can also cause death.
While smoking a dry herb vaporizer, it also produces carbon dioxide and other poisonous elements. Smoking a herb by making it into a joint doesn’t kill you on the spot but might cause health issues or death later on.
Furthermore, in vaporizing you do not inhale the smoke from combustion. In vaporizing you heat the herb, wax, e-liquid, etc that you want to vape at a certain temperature in which will create a vapour. Vaporization is produced at a lesser temperature compared to combustion.
You can vape many types of herbs that are also beneficial for health and also prescribed by doctors for certain health problems. You should switch from smoking to vaping and many are doing so. Vaping is healthier and it also saves money.
