GILLETTE, WYO. (AP) — Campbell County School District trustees have revised policies to ban electronic smoking devices in and around all school facilities.

District officials say that includes adults, who have been seen smoking the devices at school events.

The district has always banned cigarette smoking in schools and all schools are smoke-free campuses, but electronic smoking devices were not specifically included.

The new policies prohibit possession or use of electronic smoking devices by students and in private vehicles while they are on school district property. That includes to all property, buildings and vehicles owned, leased or operated by the district and all private vehicles while on school property.
