Where did you find 38 million vaping teens ages of  13-15? Did we just clone about 600+ million teenagers in the last few days doubling the entire population of the USA? Last I knew the entire population if the USA 336 million so teens are out numbering adults?  Last I saw there is just over 27,000,000 middle through high school students making just 9.4% of illegal vaping = 2.5 million that is 2,500,000.... 90.6% or about 24,700,000 DON'T USE ANY VAPING PRODUCTS! All according to the CDC NYTS.
