I remember that. The "war on drugs" was on so they couldn't have Captain America getting his power from the super soldier serum, a drug. So they wrote a story where Cap was exposed to "ice" which somehow fused to his serum laced blood, keeping him permanently high. Had to give him a blood transfusion to get it out of his system.

That was also the time where Kingpin fought Red Skull and utterly wrecked him, literally falling on top of the crimson cranium crook.
