Unidentified travelers exit the airport past a green metal container designed for "Disposal for Prescription and Recreational Drugs," set outside one of the entrances to McCarran International Airport in Las Vegas, Thursday, Feb. 22, 2018. People catching a flight at the airport can now get rid of prescription and recreational drugs, before entering the Clark County-Department of Aviation-owned property, thanks to the receptacles commonly referred to as "amnesty boxes." The first of about 20 green metal containers commonly referred to as amnesty boxes were installed earlier this month in response to county officials banning marijuana possession and advertising at the airport last year.
