It may surprise you to learn that the TSA does not actively check for drugs.

TSA agents are far more concerned with items that can put passengers’ safety at immediate risk, like explosives.

However, just because TSA agents aren’t actively searching for drugs, it doesn’t mean that they won’t find drugs – and if drugs are found, there will consequences.

How Do TSA Agents Discover Drugs?

Detecting Drugs in Carry on Bags

If you’ve ever taken a flight before, you have had to go through airport security.

This involved placing your carry on bag in a security screening bin and placing the bin on a conveyor belt, at which point it would then be scanned.

Airport scanners create detailed images of your bag’s contents, which airport security personnel will then inspect more closely if they see something suspicious.

Based on the range of energy that passes through an airport scanner, images of your items will either come up as orange, green, or blue.

This represents organic material (orange), non-organic materials (green), or metals and hard plastics (blue/black).

If an item shows up as orange on the scanner, it will be taken a look at a lot more closely because explosives are often partly composed of organic materials like glycerin, and potassium nitrate.

Weed, for example, is also organic material, so weed shows up as orange on the airport scanner.

This is usually how weed is discovered by TSA agents.

Detecting Drugs in Checked Bags

Baggage scanners typically use X-ray technology that form detailed images of luggage contents.

Anything that looks suspicious may alert airport security personnel, who will then investigate further.

Approximately, 1 out of every 10 checked bags are opened up to be physically inspected.

Again, TSA agents are not actively checking for drugs, but they may still inadvertently find drugs if something in a passenger’s luggage seems worth investigating further.

Detecting Drugs on a Person

Airports use millimeter-wave scanners and backscatter scanners.

These are whole body scanners that are designed to detect hidden weapons, tools, liquids, narcotics, currency, and other contraband.

Millimeter wave machines use low-energy non-ionizing radiofrequency waves to bounce waves off people and back into the machine to detect any items that may be concealed.

Backscatter machines use low energy x-rays that reflect the x-rays back to the machine to create chalk-like images of passengers to reveal if anything is trying to be concealed.

Today, millimeter wave scanners are more commonly used in airports in the USA.

Does the TSA Check Prescription Drugs?

The TSA does not require passengers to present their medication or even notify a TSA agent about any medication they are flying with.

The exception is medically required liquids, which are subject to additional screening, and are not limited to the standard number of liquid ounces you are allowed to bring on a plane in your carry on bags.

While the TSA does not require any medication to be in prescription bottles, state laws about the labeling of prescription medication apply.

Why TSA Agents Aren’t Concerned With Finding Drugs

The TSA state on its website that:

“TSA’s screening procedures are focused on security and are designed to detect potential threats to aviation and passengers.

Accordingly, TSA security officers do not search for marijuana or other illegal drugs, but if any illegal substance is discovered during security screening, TSA will refer the matter to a law enforcement officer.”

We assure you that this isn’t a ruse, either.

The TSA is genuinely more concerned with detecting direct threats to passengers, which means that drugs simpler aren’t a concern.

What Happens if a TSA Agent Finds Drugs?

Typically, if a passenger is trying to hide drugs on them, a TSA agent will ask a passenger to exit the queue they were in and direct them to a separate room where they will be searched.

If a suspicious item is detected in a passenger’s luggage, the TSA agent would simply open the luggage to confirm the contents of the bag.

While a TSA agent may not prioritize finding drugs, if drugs are found, they will be confiscated and the passenger will be reported to the local, state or federal authorities.

This is because a TSA agent has the responsibility of confiscating and reporting any forbidden item to the relevant authorities if discovered.

What if Weed is for Medicinal Purposes or Legal in the State?

The TSA state that:

“Marijuana and certain cannabis infused products, including some Cannabidiol (CBD) oil, remain illegal under federal law except for products that contain no more than 0.3 percent THC on a dry weight basis or that are approved by FDA.”

In short, this means that on a federal level, marijuana is still illegal to fly with.

However, states have their own laws, so the exact process and authorities’ involvement depends on local state laws.

Airport ordinances also play a role too.

For example, marijuana possession, up to 28.5 grams, is legal in airports like LAX.

What is the Best Way of Hiding Weed from Airport Scanners?

The best way of hiding weed from airport scanners it to either hide a small amount of weed in body cavities or to carry edibles.

Other ways passengers have had success hiding weed is by placing small quantities inside shampoo or moisturizer bottles.
