Do pilots get drug tested?

Yes, pilots are required to undergo regular drug testing throughout their careers. Drug testing is an important part of ensuring aviation safety by preventing impaired pilots from operating aircraft.

Who requires drug testing for pilots?

In the United States, the Federal Aviation Administration (FAA) requires drug testing for all pilots and other safety-sensitive aviation employees. Drug testing regulations apply to pilots working for commercial airlines, charter companies, corporate flight departments, air ambulances, and other operators.

How often are pilots drug tested?

The frequency of drug testing depends on the type of operation:

  • Airline pilots – Random drug tests at least once per year.
  • Charter pilots – Random drug tests at least once per year.
  • Corporate pilots – Random drug tests at least once every 5 years.
  • Flight instructors – One pre-employment drug test.

In addition, all pilots must complete pre-employment, reasonable suspicion, post-accident, and return-to-duty drug testing as required by the FAA.

What drugs are pilots tested for?

FAA drug tests screen for the following substances:

  • Marijuana
  • Cocaine
  • Opioids
  • Amphetamines
  • Phencyclidine (PCP)

Testing positive or refusing to submit to FAA drug testing results in the suspension or revocation of pilot licenses and medical certificates.

How is drug testing performed on pilots?

Drug testing involves collecting urine samples and analyzing them at FAA-approved laboratories. Here is the typical testing process:

  1. Pilot receives short notice of required drug test.
  2. Pilot reports to collection site, shows ID.
  3. Sample is collected under direct observation or in private stall.
  4. Sample is split into two bottles and sealed.
  5. Samples go to the lab for analysis.
  6. Negative test = pilot continues flying. Positive test = investigation.

Why is random drug testing important?

Random drug testing is considered the most effective way to deter and detect drug use. Pilots do not know when they will be tested, so they have to stay drug-free at all times if they want to keep flying. The random nature provides a strong incentive to avoid illegal drug use.

What happens when a pilot fails a drug test?

A failed FAA drug test has serious consequences for a pilot’s career:

  • The FAA suspends the pilot’s medical certificate, prohibiting flying.
  • The pilot must complete return-to-duty testing and clinical evaluation.
  • The pilot may be required to undergo substance abuse treatment.
  • The pilot’s license can be revoked for repeated positive tests.

In addition, airlines and other operators typically terminate pilots after a confirmed positive drug test.

Can pilots take prescription drugs?

Yes, pilots may take prescription medications, but there are strict rules around reporting and usage. Many medications are considered disqualifying by the FAA. Pilots must consult with an aviation medical examiner about any prescriptions and always check with their employer’s policies.

Do pilots ever try to cheat on drug tests?

There have been some cases of pilots trying to cheat on FAA-mandated drug tests over the years. Methods have included:

  • Using clean urine substituted from another person.
  • Diluting urine samples with water.
  • Adding chemicals to interfere with test results.

However, strict collection procedures make cheating very difficult. Substituted urine samples are often flagged as abnormal. The consequences of a confirmed case of cheating or tampering with a drug test sample are severe, including lifetime revocation of pilot licenses.


Comprehensive drug testing is critical for maintaining the highest levels of safety in the aviation industry. While most pilots would never consider flying while impaired, random testing acts as an important deterrent and safeguard. Mandatory drug screening gives the flying public confidence that sober pilots are at the controls of every commercial flight.

Airline Random Drug Testing Frequency
Delta Air Lines At least once per year
United Airlines At least once per year
American Airlines At least once per year
Southwest Airlines At least once per year
JetBlue Airways At least once per year
ExpressJet Airlines At least once per year
SkyWest Airlines At least once per year
Envoy Air At least once per year

The table above shows the frequency of random drug testing required for pilots at major U.S. airlines. All airlines must comply with FAA minimum standards of at least one random drug test per year.

Types of Drug Tests for Pilots

There are several types of drug tests required for pilots:

  • Pre-employment testing – Conducted before being hired by an airline or operator.
  • Random testing – Unannounced testing anytime during employment.
  • Reasonable suspicion testing – If observable signs of impairment.
  • Post-accident testing – Required after any aviation accident.
  • Return-to-duty testing – For pilots who failed a previous test to regain credentials.

FAA Drug Testing Program History

The FAA first mandated drug testing for pilots in the late 1980s after several aviation accidents were linked to substance abuse. Here is a timeline:

  • 1988 – FAA implements first drug testing program focusing on reasonable suspicion.
  • 1990 – Random drug testing introduced for pilots and other safety-sensitive aviation workers.
  • 1991 – FAA drug testing expanded to include pre-employment, post-accident, and return-to-duty testing.
  • 1995 – Department of Transportation raises random testing rate from 25% to 50% of covered employees.

The current FAA drug testing requirements were fully implemented by the mid-1990s. These rules remain the foundation of the program today to keep drug and alcohol abuse out of aviation.

Pilot Drug Use Statistics

Out of thousands of FAA drug tests conducted annually on pilots in the U.S., only a tiny fraction come back positive. Here are some key statistics:

  • Less than 1% test positive for illegal drugs.
  • Less than 1% test positive for alcohol.
  • Cocaine, marijuana, opioids the most common drugs detected.
  • Airline pilots test positive at lower rates than private and commercial pilots.

While overall drug use rates are extremely low, the FAA program provides oversight and deterrence to keep substance abuse at bay across the entire aviation system.

International Drug Testing Standards

Many other countries follow drug and alcohol testing standards similar to the U.S. FAA requirements. Some examples include:

  • Canada – Random testing required for commercial pilots.
  • United Kingdom – Pre-employment, random, reasonable suspicion testing.
  • Australia – Testing protocols mirror FAA regulations.
  • EU – Europe-wide rules for drug and alcohol testing of pilots and air traffic controllers.

International Civil Aviation Organization (ICAO) standards also call on member countries to establish random drug testing programs for pilots and safety-sensitive aviation employees.

Arguments Against Pilot Drug Testing

While mandatory drug testing for pilots is standard worldwide, some argue against current policies. Key arguments include:

  • Infrequent use can be detected – Pilots may lose licenses over off-duty marijuana use even if not impaired on duty.
  • Testing methods inadequate – Urine tests can only detect recent drug use, not current impairment.
  • Expensive to administer – Regular random testing programs cost airlines and taxpayers millions per year.
  • Privacy concerns – Pilots have limited rights regarding sample collection and testing procedures.

However, most experts maintain that the public safety benefits justify the costs and needs of mandatory random testing to prevent impaired pilots from flying.

Pilot Drug Use Case Examples

While rare, there have been instances of pilots attempting to fly while impaired or being caught using illegal drugs. Some notable cases include:

  • 1990 – Northwest Airlines pilots arrested for flying under the influence of alcohol.
  • 2009 – Colgan Air pilot overdosed on multiple medications before fatal crash.
  • 2015 – SkyWest pilot suspected of being impaired on duty, later tested positive for cocaine.
  • 2022 – Delta Air Lines pilot arrested on suspicion of intoxication in Minneapolis.

These incidents underscore the need for strong anti-drug policies and testing programs even as most pilots uphold stringent professional standards.

Pilot Substance Abuse Support

Rehabilitation and return-to-duty programs are vital components of the FAA’s drug testing regulations. The goal is to provide treatment rather than solely punishment. Some initiatives include:

  • Human Intervention Motivation Study (HIMS) – Peer-assisted recovery program for airline pilots developed in the 1970s.
  • Professional Pilots for Pilot Assistance (PPA) – Recovery support network assisting pilots, their families and aviation employers.
  • FAA Pilot Proficiency Program – Helps pilots regain skills and certification after time away for treatment.

These programs allow pilots who take responsibility and complete rehabilitation to return to flying safely under strict guidelines.


Comprehensive drug testing makes aviation safer for everyone on board planes and on the ground. While substance abuse issues affect a tiny percentage of pilots, mandatory testing acts as a vital deterrent and safeguard. Strict FAA oversight, rigorous airline policies, and pilot peer programs combine to keep drug and alcohol impairment out of the airline cockpit.
