There is profound clinical evidence that in the case of an overdose, the faster the 911 call is made, the sooner the response is made, and the sooner corrective medications are administered, the better the recovery, the more brain tissue is saved, and the better the outcome for the person.
There is profound clinical evidence here. There is no shortage of evidence. With a quick call and a response from 911, people recover. With a failure to call, a failure to administer the drug, people lose brain tissue and they die. It's that simple.
