I got my first LL about three months ago. It had some schedule 3 (sewmmah) AND 4 and all were confiscated. I don't think it would be any different -either at least not the first time!!!
Old post but I’ll chime in years ago when I was ordering from PK I had a pack delivered with customs tape. They took 1/3 crushed some to f with me and sent it along. Strange hunh?
