OHS and Youth at Risk

OHS Inc. cares about our community, and keeping local families drug-free. So, we help families where it counts most!

OHS Inc. provides random drug testing services at our cost, to any parent who brings their child to our Costa Mesa offices for drug testing. As parents (and grandparents) ourselves, we want the best for our children. We've learned that drug testing children randomly strongly enables them to resist today's tougher-than-ever peer pressure (i.e., "I can't! My parents drug test me!"). Random drug testing helps protect them from losing focus in school, and helps keep them on a drug-free, brain-healthy path to responsible adulthood.
