Merry Christmas, Mr. Substitute
I'm glad I looked and found out the day before I fly to Japan that bringing my Adderall could get me instant warrantless indefinite detention. That would have been SUCH a drag.
"Long story short: if the idea of spending a month or more in a windowless cell, held incommunicado, is your idea of a fun time, by all means do try to bring your Adderall into Japan."
