Why vape products should be raised from age 18 to 21 to buy

teens are getting a hold of vape products to easily and it is not doing any good for them. Their are 18 year-olds in high school who are buying younger kids the products that they want. Since the product is still so new, nobody really knows what is going to happen to people in 10 years from now. With cigs, atleast you know whats going to happen to you.
