I also know a lot more people who use cocaine (in any form) recreationally than are addicts.
> most people eventually end up in rehab or dead from an overdose
This is factually false. I think perhaps you are going off of selection set/survivorship bias. A lot of people have smoked crack. A minority of them destroyed their lives as a result.
I'm not sure this comparison holds up.

I can also believe that the absolute numbers of a victims of using drugs, alcohol, smoking is very high and so are the direct and collateral damage costs to society.
But is that relevant to the discussion in any way?
You can't snort crack, you can't IV crack. You can only smoke crack, the onset is super fast and doesn't encourage you to rapidly redose. Dosage tends to be limited by your lung capacity.
Maybe with some very impressive lung capacity?
It's easy to overdose on Cocaine HCl using any of the popular RoAs. Insufflated, the onset is very slow, enabling you to take way too much before you actually start to feel the effects. Intravenously, your dosage is not limited by your lung capacity as it would be while smoking crack.
