Weird - I've come across several doctors addicted to fentanyl too. It is actually 180 times stronger than morphine and about 100 times stronger than heroin (not 20 times - 100 micrograms fentanyl is roughly equal to 10mg diamorphine which is heroin). Plus you don't have to inject it - it can be taken transdermally as patches and they are commonly used for cancer patients/terminal illness and sometimes for chronic pain. There has been an explosion of professionals and well off people addicted to prescription opioids and it is a problem that is largely ignored.

Also the formatting on that article is beautiful. I would love to have something like that on Steemit!
