CANNABIS CULTURE – K-9s cannot smell through material. Odors permeate out and create a scent cone that the dog detects. Almost everything has pores for odors to permeate. Even plastic baggies have tiny, microscopic pores.

To prove this to yourself, place tuna inside a plastic baggie and sniff the outside of the bag. You will notice you cannot smell the fish. Wait a few hours and you will notice you can smell the permeated fish odor on the outside of the baggie.

Lead is a heavy metal and non-porous but if you hide your stash in a lead box, the K-9 handler will become suspicious.

Temperatures affect permeation. Colder temperatures slow permeation so freezing your stash in a block of ice slows the permeation to almost nothing but blocks of ice could make a smart K-9 handler suspicious.

The trick is to secret your stash in materials that have a slow permeation rate without contaminating the outside of the packaging. You must then hurry and transport your stash before the pot odors have time to permeate and develop a scent cone on the outside of the packaging.

Foil, glass, oils and cold temperatures are all good to use.

But remember, trying to mask odors does not work! K-9s smell like humans see. When presented with a bowl of stew, humans see all the ingredients but only smell one odor … stew. Dogs can separate odors with their supernatural snouts. When a K-9 sniffs the same bowl, she smells onions, pepper, tomatoes, beef, beans, etc. So if you place your herb in a plastic baggie, spray it with perfume, then seal it in plastic tubing and drop it in your auto’s fuel tank, a scent cone will develop on the outside of the fuel tank. The K-9 will enter this scent cone and smell the plastic baggie, the gasoline, the perfume, the plastic tubing and the marijuana.

This explains how my K-9 detected hundreds of pounds of marijuana hidden in gasoline tanks.

K-9s are trained to detect marijuana, cocaine, methamphetamine and heroin. They are not trained to detect mushrooms or LSD.

I hope this information keeps you out of a human cage, which is far worse than the cages kops keep their dogs in.
