Not going to want to hear this, but cr**k addiction is a psychological addiction for the most part aside from the immediate effects. The mental and emotional obsessiveness are so intense that it appears to be a physical addiction when it really isn't. The "crash" is just a coming down and is complete hell.
Not really any drugs will help, although some treatment centers may use Gabapentin, Vigabatrin, Baclofen, and a couple of others. If your friend doesn't want to quit on his own, he won't unless incarcerated for a few weeks and that doesn't always get rid of the obsession.
If he is game and will go somewhere where it isn't available for a few days, benzos could help him be mellow through the panic and angst of not having using.
No pretty picture with this one, it is quit, go to jail, or die. He has to want to quit -- that is really the key.
