"The only way to keep your health is to eat what you don't want, drink what you don't like, and do what you'd rather not." - Mark Twain, American Author 1835-1910
Vaping is not 100% safe. Life is not 100% safe either. We're all going to die and the only questions are how,when, where. Vaping can be dangerous. Batteries explode, chemicals can have contaminants, people could have medical conditions affected by vaping. Ethanol alcohol is a poison. Fatty foods, lack of exercise, vitamin deficiencies, and on and on.
People vape because they choose to do so.
