Even if they did, won’t they get a lot of false positives because of a large amount of it being sprayed hemp buds that are legal as hemp? Also, I know a lot of dispensaries get their stock like vape pens and such delivered this way already. How does that all work?
Well, if you’re stupid enough to mail some weed or any other controlled substance via USPS Media Mail, they don’t need a warrant or even Postal Inspectors to open it. As long as it is clear that the item is not media of some kind, it can be opened and documented to charge the correct postage.
Saw this before when some ding-dongs tried dumping mushroom growing kits (not exactly illegal) in the blue box at my old office. The only reason they opened them is because the fertilizer inside was causing a noticable amount of steam to come from the box (it was winter as well). All they really did was return it for proper postage because it was the wrong type.
Why would you mark your weed media mail? Mine shows up as regular first class mail. Never had an issue. It’s legal in most of the US.
To be clear, the spores are perfectly legal. You can mail order spores that come in saline solution in a syringe without trouble. The businesses selling that are smart enough to not use media mail, which of course would cross a line (fraud). I wonder why someone would risk media mail. Perhaps they thought it would be trusted as such and thus have less scrutiny.
The nuance here is you said “kit”, which suggests everything you need for growth and thus intent. Maybe you’re right on that bit. Buying everything separately would require surveillance to put all that together that you have a kit, in effect.
