He planned for the possibility in the same way I wear a bike helmet. He knew his activity carried a risk and took a step to mitigate some of the risks. Naloxone, like a bike helmet, makes an activity some people are going to do anyway somewhat less likely to be fatal. This article didn't talk about drugs like Naloxone resulting in addicts taking larger doses. I admit I lack the background to discuss whether that occurs or not.
I was thinking of a fire extinguisher analogy while reading the article. No one that owns a fire extinguisher acts in any more of a dangerous manner just because they own an extinguisher.
Heroin addicts are not regular people with a fire extinguisher in the hall.
I disagree. Please see my other long comment, My buddy that was a heroin addict was more regular and more successful than almost anyone I know.
I'm not saying heroin addicts are bad people, just that they don't always weigh their options logically. And having a safety net for overdoing it isn't a bonus.
This is where my experience trumps yours.I admit I lack the background to discuss whether that occurs or not.
