Kids are already not allowed to smoke or purchase nicotine products but millions of teenagers are still addicted to nicotine and vape like crazy. How can you enforce a ban for an entire age group? And how could you possibly justify an arbitrary ban that allows half the population to purchase and consume something and prohibits the ither half? A law that bans women from purchasing tobacco because it is harmful for a fetus would be struck down by every court in the nation, so why would a ban that discriminates against adults based kn age be any different?
