Vaping is significantly less dangerous than smoking, it’s not just some “false” perception. Without added flavors you can argue it is completely harmless and in some ways beneficial (nicotine has several health benefits).
What grease? The base is vegetable glycerin that hospitals use in their nebulizers, used in smoke generators at concerts and has been repeatedly proven to be absolutely safe for human inhalation.
Agree.

No, it's not. Filling your lungs with fine particulate matter/grease is stupid. You can still get COPD, some do. That's pretty shitty way to go.
