Hypothetically if somebody is a meth head and they mix NALOXONE NARCAN nasal spray 4 mg in their methamphetamines before they used it would it naturally neutralize any opiates that may be present in their self-medication this medication is used for opiate overdoses in theory I would think that putting this in your drugs before you actually started using it might actually neutralize it before it entered the body I'm not a chemist I have no clue but I think it would actually do the trick
Narcan reverses the effects of an overdose from opiates only. It restores natural breathing patterns. So it would not work if a person is not already overdosing on opiates. It also only works for an hour - an hour and half and the person will still likely need medical attention as most opiates stay in the system much longer.
