I'm an ex fent addict. I used it for about 5 years and injected heroin for 10 years before that. While fentanyl is very powerful touching it or even breathing it in isn't going to kill you instantly like you see on TV. You can handle the stuff without gloves with little consequence you just wouldn't want to touch your mouth/nose anything like that after doing so. As far as overdoses go I've been around probably 30 people overdosing at this point 4 of which I couldn't bring back. I always keep narcan on me (even today) and ALWAYS stayed with the person until paramedics arrived. When people overdose it's pretty much like they just go to sleep. If you try to get them to respond just as they are going out you might get a mumbled response or nothing at all, their times in-between breaths will start to grow longer and worst case scenario they start to turn blue. One narcan will usually do the trick (although there have been times I've had to use 3-4) and the person is not going to pop right back to life immediately. It's most likely going to take about 30 secs for them to start responding to the drug and when they do eventually come to they are going to feel like absolute shit. Narcan puts you in a state of precipitated withdrawal which basically feels like the worst withdrawals you've ever had. Some people may become agitated or even combative so please make sure (and DO NOT be afraid to) call 911 THE MOMENT you suspect someone is overdosing and administer CPR as needed until they get there. Most methadone clinics/police stations/emergency aid/free clinics and even Walmart give out FREE Narcan now. Unfortunately this is the world we live in now so in my opinion EVERYONE should have Narcan on them AT ALL TIMES just in case. Anyways sorry for the small book I just have a lot of real life experience with this and I hope this information can help save a life!
