What are the current rules and regulations concerning absinthe sold in the US?

I’ve found some topics through the Internet about this but they’re old and I’m not sure if things have changed or what the deal is now.

Long story short, I owed someone “real” absinthe, like he wants to hallucinate and shit. But I already am aware that absinthe has kind of been sensationalized but he didn’t seem to understand and I really owed him for something important he did for me.

So I got one imported from the Internet. But he sort of now doesn’t believe that it’s the “real thing” because apparently it’s illegal to receive absinthe from Europe. Yet. I just did. And I’m holding it in my hands right now.

The way I understand it right now based on what I’ve read – it’s not necessarily illegal to have it shipped to you, but it IS illegal to sell it. It’s the thujone content they’re worried about though, right?

I don’t know now. The more I look into it, the more I feel confused. Point is – absinthe doesn’t really make you hallucinate (right?). And it’s hard to try to convey that to him because he’s already a little off his rocker. I read that you have to have insane amounts of thujone that nobody really makes anymore in order to feel the “green fairy”.
