Many parents believe that first drink is part of growing up. A rite of passage. No real harm. But the scariest thing about addiction is, you don’t know who might be at risk – until it’s too late. Chris Herren has been there. He had his first drink at age 14, he says, breaking a promise to his mother that he wouldn’t. His father, a Massachusetts politician, remains an alcoholic, and from Herren’s own first drink came an ever-escalating addiction from beers in high school, to cocaine in college and finally painkillers and heroin during his professional basketball career. Herren, 44, shared his story Wednesday night at Rolling Hills Community Church in Tualatin in an appearance organized by Tualatin Together and sponsored by Regence BlueCross BlueShield of Oregon. Eleven years sober, Herren is now focused on prevention, taking his motivational message to more than 1 million students in communities nationwide.
