We should absolutely be using HDPP bags2. We should probably be double or triple vac sealingI also note that he was using a heat seal but I didn't see any mention of vac sealing. I think using a vac seal should add substantial benefits.While I agree with these points, the sad truth is that the vac sealing procedures the average vendor is using are probably self-defeating. To ensure that the outside of the vac bag is relatively free of contamination would require multiple compartmentalized staging areas, each with its own vac sealer. Additionally, everything would need to be handled with utmost care, like using tweezers to place odor offending substances into the vac bags. Let's be honest, it doesn't require that much sophistication to deal drugs here, and as such you can hardly expect that vendors are going to lengths like this or their equivalent, whatever that may be. While it's certainly better than nothing, I wouldn't put a lot of faith in the containment of residual contamination for someone shipping dozens of orders a day. I can just imagine a vendor's spare bedroom with a table with open bags of coke or heroin right next to their vac sealer, and their roll of vac bags resting against a contaminated as fuck scale. Hopefully it's better than that on average, but it ain't like you have to keep your operation up to code and pass inspection every three months, ya know? That said, excellent find, and great discussion.I agree that having a professional procedure to prevent cross-containmention issues is necessary. I agree with having a compartmentalized staging area for sure, but not with having different vacuum sealers.However I don't think you're giving vendors enough credit here. Some of us are amateurs to be sure, but the pros of us are using setups that wouldn't look that out of place in Glaxo or Pfizer's labs. It's not as if the Silk Road invented mail order drugs by any means. That's been going on for about a century. There are two concerns when packaging drugs, human hair/skin/fingerprints etc and the drug residue.There *is* in fact a guaranteed methodology I figured out to ensure your packages aren't contaminated before they are sent out. I'd tell it to you, but then I'd have to kill you :-XIn any case, if we are now down to the single digits in terms of nanograms per second with the simple application of vaccum sealing in triplicate with HDPP, then we're down to the 'cocaine residue on the money' level for sure, and we know the post office can't possibly stop every package with that odor signature or they would be all bankrupt within a week.Here is what I think separates the men from the boys:- mask for mouth/nose (your breath can transfer DNA)- hairnet- alcohol wipes to rub down bags with (removes the possibility of latent fingerprints)- bleach dip (removes DNA, half diluted with bottled water since bleach is both strong and viscous)- high intensity UV blacklight (more sterilization, may also reveal contaminated bags)- UV glasses (UV burns the eyes! the eyes! :-p)- 2 pairs of surgical gloves (these are special sterilized disposables used in medical operations, not your normal latex gloves)- HDPP plastic (for the reasons we've discovered in this thread!)- vacuum packing equipment - correctly calibrated milligram scales- tweezers/mini-spoon (those mini ice-cream scoops or a royal spoon do nicely)- some kind of tiny flat plastic holder/container (so the milligram scales doesn't directly come in contact with contraband)- opaque plastic wrap for the top layer (prevents visual pin-hole inspections)- generic high volume business packaging- thermal label printer (bye bye you fucking tracking dots, ha ha ha!)- exact postage to within a single stamp (some people have apparently been sending what I think of as "Mrs Weasley letters")- < 10 grams per package, special procedures for higher quantities per package.- randomly chosen return address within your zip code. - randomly chosen post boxes to drop the packages into.- in case it wasn't obvious, gloves will always be in fashion for us dropping packages in post boxes.- some of the above paid for with a prepaid card via anonymous proxy or else cash in a store (that is; anything that is going to be physically traveling through the post)
