An important way adult leaders can model healthy living is by following the policies on alcohol, tobacco, and drugs. Leaders should support the attitude that they, as well as youths, are better off without tobacco in any form and may not allow the use of tobacco products at any BSA activity involving youth participants. This includes the use of electronic cigarettes, personal vaporizers, or electronic nicotine delivery systems that simulate tobacco smoking.
All Scouting functions, meetings, and activities should be conducted on a smoke-free basis, with smoking areas located away from all participants.
