Is their anything you can do so a k9 would be unable to smell your marijuana?

Stick It Up my Smelly Ass

Destroy its nose?

Molotov it

How long of a time will there be from when you hide it to when there is a chance of the dog smelling it?

Molotov everything.

fixed.

yes, but you're probably not smart enough to do it right if we told you.

yes, hide it around something a normal dog would go after inconspicuously, such as dog food. most of the time, officer will regard as false positive and move on to the next false alert he will trigger. not fool proof, not 100%, but best option i thought of so far when riding dirty is a must.

but as for smell, no, nothing you can do. dogs smell everything/

Unless your going thru the border you shouldn't worry about drug dogs there fairly uncommon on a regular pullover unless the cop has a hunch and theres one nearby even then its still uncommon, there lazy.

I've gotten sniffed out for wearing jeans that have had drugs in them in the past. There was no evidence so I wasn't arrested, but it's pretty scary how well dogs can smell. You have to vacuum seal the stuff at least once and sterilize the exterior, as I understand. Even then it's possible for the scent to get out. Coffee beans can mask the smell, but that's become an obvious method and dogs are trained to hit on that.

Just be safe, don't bring drugs to police patrolled areas. :)
