What happens in Vegas really can stay in Vegas.
Tourists catching a flight out of Sin City can now dump their leftover legal marijuana in metal containers set up at the airport.
The 10 green bins dubbed "amnesty boxes" prevent federal transportation agents from finding pot on passengers during security screenings. The drug is legal in Nevada but still banned by the US government.
The containers were installed last week following a county ban on marijuana possession and advertising at McCarran International Airport, aiming to keep it in compliance with federal law.
They are bolted to the ground and designed so marijuana and prescription drugs can only be dropped in, not taken out.
"The amnesty boxes are offered as a way to help people comply with this ordinance," airport spokeswoman Christine Crews said in an email.
The boxes are something travellers may have seen before - at least two airports in Colorado, where recreational marijuana is also legal, offer amnesty boxes.
Las Vegas airport saw 48.5 million passengers last year. Legal sales of recreational marijuana began in the state on July 1, and they have exceeded expectations.
That's despite a ban on consuming it in public, including the Las Vegas Strip, hotels and casinos. Those 21 and older with a valid ID can buy up to 28 grams of pot and use it only in private homes.
Crews said the county aviation department planned to install 20 bins but could add more.
