One of the difficulties with drug overdose is that it can mimic other conditions, such as a diabetic coma, drunkenness, hyperactivity, shock and even just a simple tummy bug. On some occasions, the casualty may have taken the overdose purposefully, as a suicide attempt. It's important to remember that he may not be willing to receive treatment. In those circumstances, call for help immediately and stay at the scene to offer reassurance.
