There's very rarely going to be a confiscation of a package that will stop your shipment from reaching you. What will happen with enforcement is that the AG office or task force will make a purchase from your website to see if you're compliant. Those that aren't compliant will get a records subpoena and then be forced to pay a fine(s), typically of astronomical proportions based on which laws of that state you've broken and how many times. 50 shipments at 1k fine each is a lot of trouble.
State AG's can subpoena records at any time and typically they'll ask to see docs on age verification records, shipping manifests, child-resistant packaging certifications, lab tests, procedural compliance documents, etc that correspond to the laws of that state, even though they've never purchased from you. If you're not compliant, then fines and legal fees based on any shipments you've had in that state. If you fail to produce the documents or records, then you'll be forced to pay a settlement fee/fine to the AG. So warning is, unless you're compliant and keep good records you'll get porked eventually.
There are so many states with age verification and shipping restriction laws and with only a fraction of online websites following any of the actual laws,
it'll be easy money for AG's and will make them champions of protecting the children.
It's only a matter of time before subpoena's for info start going out for many states in my opinion..
