Microsoft does not allow advertising for electronic cigarettes, including cartridges, pods, and liquid nicotine solutions. The policy applies even when products are marketed as cessation aids.
Vape hardware, e-juice, disposable vapes, refill pods, and nicotine salts all violate this policy. Even non-nicotine "zero" e-juice from a vape brand triggers it because the brand is associated with the device. Microsoft enforces consistently regardless of regional legality.
