There seems to be an overwhelming deficit of information available to the general public concerning which materials and packing methods will actually put a complete halt to the natural process of scent permeation through solid objects.
Would marijuana in a welded steel box completely entrap the scents of this ever so popular drug.???
Yes, but it only works for 20 minutes.
Yes, but you can’t really stop her from screaming for help.
screaming for help???
Just once, in the early 60s.
Coffin and six feet of earth? Wait, that joke’s already been done. Sure! An airtight container – maybe a canning jar, or just can it. How about one of those air-sucker-outers with the fancy bags? Just a ziplock. What’s the commercial with the Tigers trying to eat meat? One of that!
Need to know now?
There may be little or no scent escaping the enclosed sample. But it is very difficult to get the sample into the container without any trace of the scent contaminating its outside.
idea
You could wear gloves
Perhaps if you zapped it with a 1920s style Death Ray?
Multi-layer Vacuum packing would probably work best.
Bleach or Febreze. The scent ain’t going to stick to the outside with remedies, I’m sure. If you want to get through customs in Schengen or something, I always “heard” in some coffee beans or in a ham and cured meat sandwich. That’s just what friends said – and they weren’t that smart, IMO.
I sincerely thought this thread was going to be about marinara sauce 
As did I, and I also wanted to make the joke that Mariana is a female name.

I am referring to what everyone else in law enforcement and even an episode in mythbusters how the actual air particles soak and work there way through virtually any layer of plastic becoming a part o the plastic and then the surface o the material venting off this super saturation of. obviously the surface will be bleached boiled and sterilized but i am referring to a materials ability block vapor infusion. Just about everyone and their mother swears that drug sniffing dogs have been able to smell through anything even containers which have been sealed and cleansed Please only those who actually have scientific knowledge or real stories add in comments and answers. A good place to start would be someone who can actually give a description of what a smell or a marijuana scent actually scientifically is???
Well, a smell is just airborne molecules in the form of gas or vapour, often of a volatile chemical (as that’s how they get to be airborne). No idea if the aroma that sniffer dogs are detecting is necessarily the psychoactive ingredient in Marijuana - they might be picking up some other volatile oil or something.
The other things is that materials we consider to be solid, generally aren’t. Plastic films are often porous - just to a sufficiently low extent that the sorts of things we choose to contain with them don’t leak away fast enough to matter. The size of the molecules in a contained substance will affect its speed and ability to leak through a material - which is why Hydrogen (for example) can diffuse and leak through steel.
In the book Mr.Nice about a drug smuggler one method was to put the contraband into welded shut tins and then these would be put into bigger tins full of oil that were then also welded shut. So you have an oil barrier effectively around the first tin. I believe also they had different people doing each stage so as to stop cross contamination.
This sounds like it would have to work to me as I don’t see how anything would make it across the oil barrier. The method itself was being used in the border region of Pakistan though the book was about smuggling in the 70’s and 80’s so its possibly not used anymore.
Perhaps if you buried it in a trench and then covered it with 36,000ft of seawater?
glaeken: very good use of historical facts.
Mangetout: very good step by step deduction using physical properties of physical materials
so the question is: Does the volatile compounds in marijuana that release themselves into the air or leach themselves into materials by contact actually pass through barriers such as glass or metals??
Jesus.
You come into a thread with a good idea and get ninjad on the first post.
Heh… But the narcs would send dogs down there anyway! 
I love the smell of marijuana in the morning. Smells like … apathy. Someday this war on drugs is going to end.
