Yeah it's somewhere near half a million people per year in the US die from diseases caused by cigarette smoking. Fent's body count last I checked was like 77,000.

Whether they are a fair comparison I'm not sure. It might be more accurate to say that while fentanyl can kill you, cigarettes make you live less long, rather than to say they kill you. No one drops dead from lighting a cigarette. Meanwhile, if it weren't for unreliable dosing due to black market pressures, I'm not sure regular, reliably dosed opiate usage would kill you slow the way cigarettes do.[citation needed] Anecdotally, I've noticed that ex junkies often look ten years younger than they have any right to.
