Permeation isn’t just a process of gasses going through pores or openings in the container. It is the process by which the contents, at a molecular level merge through the molecules of the container, not leaks or openings per se.
When I said that to date no such material has been identified for the purposes of drug smuggling I mean exactly that and despite the search having certainly been very thorough as explained further in my post.
But as I posted, if large-scale drug smugglers aren’t using materials that prevent dogs from detecting the marijuana it is because they are logistically impossible to implement, even if theoretically possible. Otherwise they would and I consider that to be a very big and well funded research department.
Read the book, “Blow.” That’s right they made a movie out of it in 2001. In the book, George Jung ran a canning operation to put contraband into cans, run the cans containing the contraband through a dish washer, and then labelled the cans as if they were ravioli, beans, and other things to get them through customs and into America.
So, yes, it is possible to completely seal something up so that even a dog cannot smell it.
Frankly speaking, US Customs should get bears to smell for contraband. A bear’s nose is 7 times more sensitive than a dog’s
I haven’t read the book or seen the movie but I always try to remember that not every factoid in a book is true, or as important to the real story, as they might have the reader believe even when it is based on a true story.
From what I can read on the wikiabout him it looks like his career was pretty much a long string of getting busted for marijuana, over and over, while only semi-successfully smuggling cocaine and finally winding up where he is today, in prison.
I’m not really sure you can hold this up as a testament to the effectiveness of whatever anti-permeation scheme he may have cooked up in the 70’s using canned goods. It obviously didn’t work out to well for him overall. A container that could effectively shield the odor from dogs for a reasonable amount of time would, especially today vs. the 1970’s, be extremely suspicious to humans if not dogs.
I’m not sure what made you think I misunderstood what “permeable” means.
There’s a big gap between “logistically impossible” and impractical. Setting up a factory that puts marijuana in hydrogen-containing grade canisters and washing them before shipping on a coffee boat may just be cost ineffective. Drug exporters know that a certain percentage will be found and add that into the costs. An aggressive plan to eliminate odour would have to be less expensive than the smaller percentage of loss that is attributed to sniffer dogs.
Yeah, until one of the people you sprayed tells security about the crazy guy outside the airport spraying everyone with chemicals. Do you seriously think that’s something a person could pull off discreetly without being noticed?
I concede, dogs do have to be somewhere they can breathe in order to sniff for drugs. (at least, I think). Stay tuned for sniffer dolphins at the high seas.
Do dolphins have a sense of smell?
Dolphins lack olfactory receptors (the olfactory tract and bulb only exist in the fetal stage of development) and therefore, do not have a sense of smell.
It was a joke. But yes they abandoned their sense of smell when they made the water a full time home. They do have things like echolocation, and an ability to detect electric fields, and other surveillance techniques that the port authorities and coast guards and law enforcement agencies already have.
The trip from shore to downtown is still dog territory though. But it’s a big ocean and a big country. Out of all the subs that get captured I’m sure there are plenty that make it through. (and a quick walk through downtown Anytown USA would seem to corroborate this.)
A quarantine dog picked out my bag at an airport in Australia once. It had had a piece of fruit in it a few days before, but nothing since. From the reaction of the handler, I gather it happens regularly.
