An amnesty box is a locked, one-way drop container placed before a security checkpoint where you can anonymously surrender a prohibited item without being arrested, cited, or identified for having it. You’ll see them most often at airports in states that have legalized cannabis, on military installations, and at some government buildings with screening. The protection is genuine, but it is narrower than most people assume: it covers your possession of the item at that moment, nothing more, and only if you use the box before anyone finds the item on you.
How the Drop Works
The box is sealed and positioned before metal detectors or search points. Items go in through a slot designed like a bank deposit, so nothing can be retrieved, tampered with, or stolen once deposited. The established policy is that no one asks what was dropped or who dropped it. Law enforcement collects the contents on a schedule, but no effort is made to identify depositors. Surrendered items are treated as abandoned property rather than seized contraband, and that reclassification is the legal mechanism that keeps you out of trouble.1Office of Justice Programs. Amnesty Boxes – A Component of Physical Security for Law Enforcement
There is no paperwork, no identity check, and no database of amnesty box users. Authorities do not pull security footage to figure out who deposited what. The act is treated as voluntary compliance, not as a confession.
Where You’ll Find Amnesty Boxes
Airports
Cannabis amnesty boxes have appeared at airports in states where recreational marijuana is legal, including locations in Chicago, Las Vegas, and parts of Colorado. They sit near TSA checkpoints so travelers can get rid of cannabis products before stepping into federal jurisdiction, where marijuana remains illegal regardless of state law. Each airport decides on its own whether to install them, so coverage is uneven. Some airports without boxes simply direct passengers to regular trash receptacles.
Travelers also use airport boxes for small knives, loose ammunition, and other items that would stop them at the checkpoint. Local police typically manage the boxes and empty them on a regular schedule.
Military Installations
Every branch of the military runs an ammunition and explosives amnesty program. You can turn in munitions anonymously, with no questions, no paperwork, and no investigation or disciplinary action triggered by the turn-in.2U.S. Army (Fort Jackson). Ammunition and Explosives Amnesty Small arms ammunition (.50 caliber or smaller) goes directly into a designated amnesty box. Anything larger, or anything damaged, leaking, or unstable, should not be moved; call the nearest installation’s 24-hour hotline and Explosive Ordnance Disposal personnel will recover it.
Government Buildings
Some courthouses, correctional facilities, and federal buildings place amnesty boxes or lockers outside their screening areas. The principle matches the airport version: you get one chance to surrender a prohibited item before the metal detector finds it.
What You Can Deposit
Amnesty boxes handle items whose possession would cause a problem at that specific location. Common categories include:
- Cannabis products such as edibles, flower, vape cartridges, and concentrates at airport boxes in legal-marijuana states.
- Small weapons and blades, including pocket knives and box cutters that end up in carry-ons by accident.
- Ammunition, including loose rounds in luggage and, on military installations, small arms rounds of all calibers that were found, misplaced, or improperly removed from storage.3United States Army. Department of the Army Amnesty Program Policy
What Boxes Won’t Accept
Some items belong in a different disposal channel, and putting them in an amnesty box creates a bigger problem than the one you’re trying to solve.
- Hazardous materials, bulk explosives, and anything flammable, leaking, or unstable. These require specialized disposal, and on military bases they require EOD pickup rather than a box drop.
- Firearms. Most airport and building amnesty boxes are not designed for handguns or long guns. Many jurisdictions run separate surrender or buyback programs with their own no-questions-asked rules.
- Needles, sharps, and drug paraphernalia. Airport cannabis boxes are generally intended for legal substances, not injection equipment, which needs a biohazard container.
Where the Legal Protection Stops
The amnesty covers one thing: your possession of the item at that moment, in that place. It does not reach anything else connected to the item. Surrendering a weapon doesn’t grant immunity for a crime previously committed with it. Dropping cannabis in a box doesn’t retroactively legalize an illegal purchase. If a deposited item is later matched to a known crime, law enforcement isn’t obligated to look away from that fact; the amnesty protects you as the depositor, not the item’s history.
The second limit matters even more. Protection applies only if you surrender the item voluntarily, before anyone finds it on you. Once a TSA agent spots something during screening, or a K-9 alerts to your bag in line, the window has closed. The military program states this directly: if law enforcement encounters ammunition or explosives on your person, or in a home or car, it is too late for amnesty to apply.2U.S. Army (Fort Jackson). Ammunition and Explosives Amnesty Intent to use the box doesn’t count. Only the completed deposit does.
On military installations, the shield is written into policy: an amnesty turn-in cannot serve as the basis for initiating an investigation or prosecution, and it’s exempt from the investigation requirements that would normally apply to recovered munitions.3United States Army.

What Skipping the Box Can Cost
If you bypass the amnesty box and TSA finds a prohibited item at the checkpoint, the civil penalty can run up to $17,062 per violation per person.4Transportation Security Administration. Civil Enforcement The amount depends on what’s in your bag:
- Knives and bladed weapons: a first violation may draw a warning notice. Later violations carry penalties from $450 to $2,570.
- Non-firearm weapons such as BB guns, stun guns, and tasers: $450 to $2,570.
- Loaded firearms, or unloaded firearms with accessible ammunition: $3,000 to $12,210 for a first violation, plus a criminal referral. Repeat violations run $12,210 to $17,062, also with a criminal referral.4Transportation Security Administration. Civil Enforcement
Those are only the TSA numbers. A criminal referral pulls in local law enforcement separately, and depending on the item and the state, you could face criminal charges on top of the federal fine.
Prescription Drugs Use a Different System
Amnesty boxes are not the right disposal channel for prescription medications, especially controlled substances. The DEA runs a separate program with more than 16,500 authorized collection sites at pharmacies, hospitals, and police stations that accept unused or expired medications year-round.5Drug Enforcement Administration. Every Day Is Take Back Day Under the Secure and Responsible Drug Disposal Act, only certain people are authorized to deliver controlled substances for disposal: the person who was prescribed the medication, someone managing a deceased person’s property, or a long-term care facility acting on behalf of a resident.6Drug Enforcement Administration. Disposal of Controlled Substance Prescription Medications If you come across abandoned medications in a setting like a clinic and can’t return them to the owner, contact local law enforcement or the nearest DEA office rather than using an amnesty box.
