Which of the following is NOT an exception for mailing cigarettes and smokeless tobacco?

The focus of the question is on identifying which scenario does not qualify as an exception to the USPS regulations on mailing cigarettes and smokeless tobacco. The regulation explicitly prohibits the mailing of these products, but there are specific exceptions outlined in the rules.

The exception for personal gifts does not apply to the mailing of cigarettes and smokeless tobacco. This is because the USPS regulations aim to restrict the shipment of these products in order to maintain public health and safety, as they are associated with health risks and regulatory issues. Therefore, mailing these items as personal gifts is not permitted under current guidelines.

In contrast, there are clear exceptions for mailing cigarettes or smokeless tobacco for business or regulatory purposes, which may involve shipping to businesses that deal with tobacco products or regulatory entities that require samples for compliance. Consumer testing or public health research can also qualify as legitimate reasons for mailing these items, as they are often conducted under strict regulations that ensure safety and compliance with health standards.
