Has anything passed?

The obvious question. YES! Visit our Results page for the current list of passing products.

How close does a dog have to be to smell it?

We get this one A LOT! Here’s the deal. There are so many variable that it’s impossible to know. Quality of the product, how smelly the contents is, training of the dog, wind… I can go on and on. But the key to minimizing risk (and that’s what we’re really trying to do here) is looking for a quality construction and taking care of your containers.

Where do you get the bags? Do companies send you stuff?

Sometimes we buy them, sometimes companies send them, and sometimes friends send us stuff too! No matter how we get them, they go through the same testing protocols, with no bias or favors to the manufacturer. The dogs don’t care where it comes from, only what’s inside.

What scents do you use?

We use cannabis! The “smell proof” products are advertised to the cannabis community through smoke shops, social media, and events. We felt it was important to use real scent rather than synthetic to add authenticity to our work.

Do you smoke it afterwards?


How do you prevent scent contamination?

Lots of gloves! Every time we touch our odor source we change gloves before touching the the bag, box, or whatever type container we are testing. We take great care in how we handle everything to prevent accidental contact between cannabis products and items being tested.

What is your testing method?

We have a standardized testing method to ensure fair, accurate, and reproducible results. The materials used include one advertised smell proof container, two cannagars weighing 3-4 grams each, and two detection dogs trained to identify cannabis.

1- We place one odor source into the container (without touching it to the outside surfaces), close it as the manufacturer intends, and hide it somewhere at the search location with the dogs and handler out of view.

2- Then we hide the second odor source to act as a control, again with the dogs and handler still out of view.

3- After the first dog searches the area we repeat steps 2 and 3, without removing the odor from the container, and begin the search with the second dog.

4- Carbon lined products only. After completing the above, we leave the scent in the container for a minimum of 24 hours and then test again. This is to allow the carbon ample time to absorb the odor.

-To prevent the dogs developing habits we always use a new location and of course new containers.

-We have also started occasionally introducing empty, and previously tested, containers into our searches to demonstrate that the dogs aren’t alerting to materials used to make it, but what is contained inside it.

Why do you do this?

Short version: Because people deserve to know!
