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?
A friend of mine used to ship pounds at a time through FedEx. He would ship about 20 packages every fall, half of them made it to their destination, but he and the recipients were never contacted about it. His thinking was that if someone at FedEx noticed, they would just keep it, while someone at USPS would probably get the wheels turning for prosecution.
