If you have not seen HBO's documentary on addiction I would urge you to go to the link below to their website.

 You can not predict who will become addicted and who won't.  But for those who do become addicted and for their families, the information in this HBO special is so hopeful.  I'd urge everyone to watch the special on HBO On demand or at least link to the site above.
