It is not niacin that is gonna be in the med..... I just did a six month study on a new drug. It was OC mixed with Narcan. They are easily crushed with no gel but because its an analgesis mixed with an antagonist it makes it impossible to abuse. You cannot break the med in any way or the two ingredients counteract eachother. A good thing about the narcan is it somehow reacts in the GI tract and prevents the constipation that often comes with opioids. The medicine definately kills the pain if u don't manipulate the original form.
