Not everyone lives in the US. In my country, disposable vapes are banned, so everyone selling or buying them is committing a crime.

Banning vapes is stupid. Its basically just handing a monopoly to organised crime.

Even in the US, selling to kids is illegal in most states, so the same issue applies: kid can't buy vape at store, kid goes to adult who is likely to be criminal to get them to buy for them, now kid is vulnerable to exploitation.
