Do people get in trouble if the USPS confiscates stuff, like dab wax?

I worked for 5 months at USPS last year as a rural carrier and I'm sure I delivered some weed in packages before. Some boxes reeked but we delivered them anyway because I wasn't about to ruin someone's day/life going through their mail and bringing it over to inspectors....also the USPS does LOTS of illegal shit when it comes to spying, going through peopele's shit, gossiping about residents in the mail room....

If you think about it, USPS is the only part of government that literally touches every single person in America (and puerto rico) every single motherfucking day, come rain, shine or snow. They know A LOT about each person. I'm so glad I resigned.
