You see how it says “illegal” there? In smuggling cases there has to be this other thing called “intent” for it to have been illegal.
If a Mexican gets some codeine at a Mexican pharmacy, forgets it in their bag, and flies into the USA we don’t pay tax money to imprison them for years. We take it, ban them, and send them back.
Why? Because they are careless, not smugglers.
You are wrong, that is not true at all. We confiscate the items, sometimes deny entry, and sometimes ban future entry. It happens all the time with pharmaceuticals, produce, and any number of other goods that are legal elsewhere but not here. Spending tax money to imprison people for years over minor cultural differences and misunderstandings is absolutely brain dead policy.
There are already 5 cases like this because this is a super common mistake and T+C recently implemented a change in their policy for handling it.
