Quote from: Flakes on August 13, 2012, 07:43 pmI have used Static Shielding Bags used for electronics along with a sealer to seal herbs.2 layers, no vacuum, sealed and wiped with acetone in-between, and there was no smell 2-3 weeks later on a sample. The same qty could be picked up from 10' away after spending a night in a baggie stuffed inside a glass jar...I use large (12x12) bags which I cut down to size and seal on all 3 open sides (after cutting). Stuff inside a slightly larger bag, seal again.the bags are made of polyethylene, aluminum, polyester, and "static disappative" layers... they're also opaque.You're making a good effort, but we need to be doing experiments far more scientifically, I mean there is simply no comparison between a canine nose and a human one. If smelling was seeing, then we would be the equivalent of cave bats in the kingdom of the mammals.So, getting the raw data, getting numbers is super important so you have a solid foundation. It is clear from the academic whitepapers that multiple layers are good if handled correctly in a clean staging area, taking the particulate rate (our key metric) of nanograms to hundreds per sec. However although this massively deters both electronic and canine noses in terms of the practical business of prioritization when faced with many packages such as at the postal conveyor belts in sorting offices, you ideally want the PR at single digit ng/sec so that even an experienced dog or the best electronic detection equipment fails when presented directly with a package to alert on. So, we need access to equipment for testing (to produce some blackpapers, ha ha I'm so funny... don't give up your Int smuggling career just yet pine!).In the meantime, upping your layers to 3, ensuring your staging area practices are clean and possibly putting packages into ice water before transmission sound to me like reasonable precautions. Good job on the acetone wipe btw, more people should be doing that.Quote from: mochill on August 14, 2012, 09:11 amI have a question: does glass (jars/containers) keep in MDMA molecules pretty effectively? Let's say I put some crushed MDMA into a cap, and then into a ziplock, then into a glass jar. Would that be sufficient enough security, or would the mdma go through the glass (or perhaps the plug for the jar)?Yes our pals at OVDB are fond of using mason jars because it prohibits the Customs pin test from working and they may have a requirement to be distributing vials of liquid LSD occasionally. However two issues are that glass is infamously not so opaque, and more importantly the transmission of glass receptacles through the postal system (IMHO of course) is subject to breakages and also can suggest the carriage of a liquid (or allow such an interpretation to be chosen if you understand me), which is a red flag to a postal service constantly on the look out for mail bombs. Maybe it was different pre 9/11, but that's changed, I would hare hundred miles away from giving the postal inspectors any hint of explosives traversing the mail system, because then they would have much greater leverage to open anything they want. USPS affords drugs in the mail some degree of protection due to legal rules that don't apply to private couriers. USPS folding, which it almost certainly will, will introduce problems for unsophisticated drug smugglers later on.It is normal for small quantities of drugs of all kinds to (most illicit packages picked up are probably initially imagined to be steroids or foreign RCs) travel through the postal system. A couple of grams of MDMA vacuum packed a couple of times with LDPE or HDPP or Mylar, and splitting larger quantities above 10 grams into multiple packages is probably the optimal choice in today's present environment (suggest using a little plastic container inside the layers so it's not messy, or possibly a foil sachet like the sort that comes with your quick cook noodles).In all honestly, I think proper staging area handling is more of a problem right now than the packaging technique (but if you don't use packaging then you don't have a problem, you are the problem lol). Judging from what SR's informants say inside the postal system, often dogs will practically attack a package, tear it to shreds while completely ignoring the drugs vacuum packed that fell out of the exterior package. Clearly the vendor screwed up with his handling policy. Either his staging area was not clean or he touched the exterior/interior of the vacuum packaging with drug particulate on his paws. Or god forbid he went off and smoked a joint to relieve stress.As such, it might behoove people to be closely examining the strict staging area protocols observed by those scientists that work in cleanroom laboratories in the nanotech and biomed industry.Remember above all else, this is only half about avoiding interceptions of product, it is also about decreasing risks for the vendor, that is arguably far more important than merely losing business.
