On the rainy fall morning of their first appointment, Dr. Mark Willenbring, a psychiatrist, welcomed a young web designer into his spacious office with a firm handshake and motioned for him to sit.

Addicted to heroin, he had tried more than 20 traditional faith- and abstinence-based rehabilitation programs. In 2009, a brother died of an OxyContin overdose. Last summer, he attempted suicide by swallowing a fistful of Xanax. When he woke up to find he was still alive, he overdosed on heroin.
