I think the wiki page you linked sums it up perfectly:
There's nothing in this character. It's a joke, and a weak one at that.
From a creative standpoint, his character is gold. I'd take him over the joker easily.
-80's throwback design
-Feels no pain due to being heavily sedated under the infuence of drugs
-Superstrength, superspeed, super reflexes
-Flamboyant quirky personality
-You can use his character to shoehorn a story about the illegal drug trafficking industry and the war on drugs.
-witty one-liners, colorful design
-Worships cocaine as a deity
-likeability, novelty factor
-his only weakness is cocaine dependence, can be played up for laughs or for serious
The funny thing is despite his quirkyness, he is a believable heavy hitter. You can actually make him whip someone like aquaman's ass and it wouldn't be too much of a stretch
