What would happen if Superman did heroin?

Or for that matter, what would happen to any superheroes who did heroin (I know this is a broad question, but I assume most answers would be the same). Would it affect their powers in any way? Would they become addicted?

Well assuming you could find a way to inject Superman in a way that didn't expose him to a lethal dose of kryptonite. The heroin would probgably have no effect on his Krytonian physiology. Unless it was made from Super Kryptonian poppies.

The most intersting hero to give Heroin to would be the Flash. His extra fast metabolism would break it down quickly but from his Point of view he'd be stranded in a blissful experience for hours, days or weeks while the outside world only experienced a few seconds at most.
