my experience

I took a whole bag into LA custom in 02, and was checked by some Oriental Indian looking persons. they took some samples of my herbs to test without asking for any invoice, i told them these were for my cancer. Then they released me.

In 03, all my luggages were herbs. I pushed all these herbs before these custom officails in LA custom again, they did not stop at all.

Depends on ur luck, Good luck!
