Do any of the NCIS cast members smoke cigarettes or smoke marijuana?

Answer 1

As of my last update, specific details about the personal habits of NCIS cast members, including smoking cigarettes or marijuana, are not widely publicized. While some actors may have mentioned their smoking habits in interviews or on social media, such information is often private and may not reflect their current lifestyles. For the most accurate and up-to-date information, it's best to refer to recent interviews or official statements from the actors themselves.
