Can you bring a vape or e-cigarette on a domestic flight in Vietnam (Cam Ranh to Hanoi)?

Cam Ranh Airport (Nha Trang) has standard security screening on domestic routes. Travelers suggest packing a vape in carry-on luggage alongside other electronics (e.g. a portable gaming device) rather than carrying it in a belt pocket, as this draws less attention from security.

The same question was raised the day before departure: whether to carry a vape in a belt pocket or in carry-on among electronics. The consensus is that tucking it in carry-on with other gadgets is safer, as it blends in as a regular electronic device during screening.
