I fully understand that both alcohol and tobacco use are bad and not the healthiest of choices. Both involve risks in varying degrees and depend on many factors. However, what I don't understand is how prohibiting online sales solves anything. Alcohol as a federal age limit and sales are regulated by the states. Alcohol sales are mostly face to face (some like Ohio also allow online ordering and incoming shipments of alcohol), and it's up to the sellers to verify the age, but clearly that doesn't really work in all cases. Tobacco rules seem to be mostly controlled by the states right now, although more and more of them are transitioning to a 21 year age limit. Fair enough, make that a federal thing, but either leave the sales to the states like alcohol, or, solve the age verification issue for online sales with a technological solution. Technology and services exist to verify identities and ages online. Financial institutions use them already for new accounts, etc. That seems like a better solution, but I clearly don't understand the bigger picture of what's happening!
