I need to convince my friend in Plumsteadville, Pennsylvania, to go to a drug rehab. How?

I have just learned from someone else that my friend is struggling with heroin addiction. I really want him to get himself treated. I want to know how I can find drug rehabs in his area so that I may ask them how to convince him.
