buy one of those vacuum sealing machines. get the smaller sized bag and compress as much as but not over around 7g's(I think this what I heard not sure). then re wrap as many time as possible without making it look suspicious and put it in a regular envelope in the mail.
I think I read that drug dogs arn't around normal mail as often because there's so much of it. but I could be wrong so I can't firmly suggest trying it
as I stated earlier, dogs are a bit outdated for agencies with the funds..... read further.... (the following is a cut/paste from the first relevant document I found)
The original pinpoint search, the drug dogs sniff, has built-in limits. A German shepherd is a cumbersome piece of biotechnology, making suspicionless sweeps during routine traffic stops the exception rather than the rule. But chemists and engineers are developing a variety of electronic sniffers that are competing to make Fidos schnoz obsolete.
DrugWipes, for example, are small, swab-tipped devices. Wipe the tip along a surface, or a sample of sweat or saliva, and in two to five minutes a simple indicator window reveals whether drug residue is present. Manufactured by the German firm Securetec, DrugWipes have been used by more than 2,000 law enforcement agencies in the U.S. since the late 1990s, and theyre increasingly popular among schools and private employers as well.
DrugWipes have limitations: Theyre single-use devices, and while the basic model is inexpensive (less than $10 per unit), each picks up only one specific type of drug residue. Even with a relatively low per-unit price, the cost of sweeping a school or a parking lot can mount quickly. For more versatility, cops can turn to General Electrics VaporTracer, a seven-pound handheld particle sniffer that can test for a wide range of drugs and explosives in only a few seconds.
The VaporTracer and its nonportable cousin, the Itemiser, are already used in airports to scan luggage for explosives. With a price tag of $25,000 to $30,000, the VaporTracer is unlikely to become standard issue for beat cops in the near future. (G.E. estimates that about 4,000 are in use worldwide, most for explosive detection.) But researchers are developing ever faster, cheaper, and more sensitive electronic noses.
Among the technologies in the offing is the desorption electrospray ionization scanner. It uses charged droplets to lift particles from a surface and into a mass spectrometer, which can break down and analyze the components of any substance down to the molecular level. Its currently a desktop-sized machine, but its creators, a team of researchers at Purdue University, hope to develop a portable version that can fit in a backpack within a few years. The Purdue teams head, Graham Cooks, guesses such a device might cost about $4,000. Thats not exactly cheap, but its thousands of dollars less than a well-trained drug dog costs.
Meanwhile, scientists at Georgia Tech have developed prototype scanning technologies based on a penny-sized surface acoustic wave chip, which works by measuring disturbances in sound waves as they pass across small quartz crystals. This dog on a chip sensor is coated with a thin layer of cloned antibody proteins that bond to a specific molecule, such as cocaine or TNT. The sound waves passing through that sensor can then be compared with an uncoated control crystal: Differences in the waves mean the chip has picked up trace amountsas little as a few trillionths of a gramof the target substance.
