Is Brandon Novak still clean?

I just finished reading "Dreamseller," and it seemed like it ended on a happy note, but I couldn't tell, because he still called himself a junkie. I don't know if he means that he was once a junkie, so he's always a junkie, or not. But is he clean as of now, in 2010, two years after his book was written? It'd be such a shame if he wasn't, after everything he's put himself through.. Thanks.
