It's important to emphasize that the opioid antagonist drug Narcan, or naloxone, will only effectively reverse an overdose caused by drugs in the opioid category such as heroin ["Saved by school nurse," News, Nov. 19].
There is no evidence that Narcan will reverse the life-threatening effects of overdose caused by any other category of drugs, including synthetic marijuana. The public should not view Narcan as an antidote against all drug overdoses.
