Sorry, but that excuse doesn't fly. If it's illegal in Russia it doesn't matter if it's an Rx or not or if she brought it from Alaska, e.g., where it's legal. It's still illegal. It was just stupid for her to bring it there, or any other country where it's illegal. Not only that, but there's plenty of other alternatives for pain medication that she could have used instead, especially when travelling to any foreign country. There are proven NSAID's that are more effective for chronic pain. She just wanted to get high in addition to having pain medication. Dumb, dumb, dumb.
Glad she's back though, but boy she sure is dumb for that snafu.
