    Can You Fool A Drug Sniffing Dog?

    Dogs are truly men and women’s best friends. However, to weed lovers, the canine, with its super smell, can also be their worst enemy.

    How Good Is a Dog’s Smell?

    A dog’s sense of smell is said to be 40 times greater than humans. Additionally, canines are able, with pinpoint precision, to differentiate separate smells from one another. So, to put it bluntly, you are paddling up SH$# creek without a canoe when attempting to hide your drugs with either a specialized odor-proof bag or some other type of vacuum packaging.

    A Dog’s Amazing Sense of Smell

    The typical dog’s nose has 300 million smelling (“olfactors”) receptors in its nose. To put this number in perspective, humans only have six million olfactory receptors. This means that a dog has a sense of smell that is around 50 times greater than the average human.

    According to Pheonix Vet Center, a dog’s sense of smell is so powerful that it can detect an illicit substance at only one part per trillion. This is equivalent to finding a drop of liquid weed concentrate, in 20 Olympic swimming pools. I haven’t verified that statistic. But, one thing I do know is that dogs, when trained, are capable of smelling just about any substance.

    What Can Drug Sniffer Dogs Find?

    Dogs have been, successfully, trained to find the following illegal substances and also illegally traded prescription drugs.


    • Coke

    • Heroin

    • Meth

    • Molly

    • Bath Salts

    • Spice (AKA K2)

    • Kratom

    Additionally, a drug dog can detect the following legally prescribed prescriptions:


    Fentanyl-A highly powerful synthetic prescription pain reliever that comes in either a pill or powder.

    Prescription Pain Relievers-Like Vicodin, Percocet, Oxycotin, and more.

    What About The Vape Cartridge?

    Vape Pen

    A police dog, that is trained to smell weed, will be able to smell weed in your vape cart. So, your potential weed vaporizer loophole is unfortunately a no-go.

    Would Masking The Pot Smell Work?

    By masking, I mean trying to override the marijuana smell by adding another powerful or enjoyable scent in an attempt to trick the police dog. For example, smugglers have attempted and failed with trying to mask weed with perfume, coffee grounds, baking soda, and even peanut butter.

    As stated previously, a drug detection dog with exact precision can differentiate between different smells. This means that, for example, a dog’s nose will be able to separate the cannabis smell from the pungent smell of baking soda.

    Any Limitations on A Dogs Detection Abilities?

    Previously, I wrote an article on whether dogs can detect cannabis edibles. In summary, the article stated that dogs need to be specifically trained to detect certain substances. So, unless a drug-sniffing dog is trained to detect edibles, they will likely not be able to recognize an edible gummy or chocolate bar on you. Therefore, a drug-sniffing dog can only detect substances that they are trained to find.

    Do Not Bet Your Freedom On a Drug Detection Dog, Smell Proof Bag

    Skunk Sack Storage Bags - (6, 8.5" x 10")

    This information was gathered from High Times, one of the most reputable and respected cannabis magazines and websites on the Internet. So, it is not from either an odor-proof bag company that is trying to sell you their product. I.E. Skunk Bag. Neither is the information from drug rehab or law enforcement agency that wants to scare you from trying cannabis.

    Hight Times’ conclusion was that a smell-proof bag is essentially non-existent. The reason being is that almost all commonly used air-tight containers contain small holes where the marijuana odor can escape.

    The only question is how long it will take for the weed smell to leak and not when will it happen. The smell escape occurs with all plastic containers (I.E., Freezer bag, Mylar bag, vacuum bag, and even the mason jar)

    The Problem With So-Called Odor Proof Bags: Cross-Contamination

    A double sealed vacuum bag or a specifically designed airtight container, might for a while hide the weed scent. Law enforcement officials have even admitted under oath, that under a CONTROLLED environment, a bag might even be, in fact, smell proof.

    Notice, though I emphasized a “CONTROLLED” environment, such as a sanitary laboratory. It is likely however that your house does not have lab-quality, sanitary standards, which will result in the airtight container being subject to cross-contamination. For example, after having a few tokes on a joint, you touch the weed container with your ungloved hands. That simple act would ruin the effectiveness of your odor-proof bags. Watch the below video for a further explanation.

    If You Are Going To Try, What Should You Do?

    First of all, I don’t recommend that you take any illegal drugs with you if it is likely that you will encounter law enforcement. The reason being is that the punishment can be severe in certain US states and in certain overseas countries cannabis possession can result in life imprisonment or even the death penalty. This cautious approach is even recommended by High Times.

    Per High Times, the only ways for you to potentially fool a drug dog is to do the following:

    Vacuum Seal Frozen Weed -The colder the temperature the LONGER IT WILL TAKE for the cannabis smell to escape. Please note, I said the longer it will take. Freezing weed will only slow down the process and not stop it. So, this will only work for short trips. And is

    Led Box-A tightly sealed, Lead box, per High Times, is the ideal way to potentially fool a drug detection dog. However, this solution is far from ideal as lead is a hazardous substance. (Although you can fix this by packing the weed beforehand). Therefore, you will have a hard time finding a suitable, smell-proof, lead container. (I was not able to find any LED metal containers on Amazon and even a Google search.)

    Final Thoughts

    You are fighting an uphill battle if you think you are going to be able to hide weed for a canine drug dog. So, my advice is to not even attempt to try to fool the drug dog. And, practice common sense when you are traveling with illegal drugs. For example, obey the speed limits, make sure your car is registered, tail lights working, and of course, do not smoke weed in your car. Better yet, move to a state where weed is legal! If that’s not possible, I would visit weed-friendly states, like Colorado, Oregon, and Washington.
