The numbers are quite high. Research says probably someone with PTSD will have 50% or more chance of having a substance abuse problem. The way we treat it, our clients have an OSI with the substance abuse problem. The issue is first the identification, because a lot of our clients will not admit they have substance abuse problems, so screening is very important. We're looking at training the Veterans Affairs staff on that, OSI clinics. This is one thing.
Then the engagement means that someone can have a problem but doesn't want to do anything about it. We have service providers, so we could refer clients and pay for sessions with service providers. We also have six providers across the country who offer in-patient service for up to two months' comorbid PTSD and substance-abuse programs. So we have them across the country, and they are very effective. They are working well.
