Our Two Community Service Programs

OHS Inc. cares about our community and keeping local families drug-free. So, we help families where it counts the most, with our unique "Youth at Risk" ("YAR") and "Parents Taking Action" (PTA) Programs!

According to the National Institute on Drug Abuse, by the time they are seniors, almost 70% of high school students have tried alcohol and FULLY 50% have tried an illegal drug. OHS Inc. provides random drug testing at our cost to parents who bring their children to our Costa Mesa offices. Testing children randomly strongly helps them to resist today's tougher-than-ever peer pressure, "I can't! My parents drug test me!"). Learn why it's never too early to begin testing, and let us help you!
