Me and my brother were bored one day and we decided to go to camping (on private property not owned by us). So of course the cops were called and they had to come and tell us to leave. So the cop walked with us back and when we got there it was a K9 unit. I had a test tube full of marijuana on me. The window was rolled down where the dog was at and I was about 10 feet away from it. It didn't bark, it didn't do anything. Do you think it could have smelled it through the plastic test tube I was carrying?
Probably not but cops can track your location from things you post on the Internet -.- it's an ip address.
Yes, they can smell it through almost anything. Usually they smell the trace amount on the outside of the tube.
the only time a k9 dog would notice the grass is if it was trained to. Not all K9 dogs are drug dogs. Myth busters has an interesting episode on how hard it is to sneak drugs past a drug dog. See if you can find that episode and watch it. They did all kinds of things to fake out the dogs and nothing worked...
