I know overdose is when somebody has over and above what the body can tolerate. We do know that, frequently, it's not just a single substance that is causing the overdose, and it may be taken intentionally or unintentionally.
We know that people can respond and if they make a plan, can contact emergency services. People can respond and use the naloxone very effectively as a bystander. We're well aware that people who are in a situation can call 911 and it really does make a difference.
