what manga is this from?

It's not from a manga it's from a comic, Hellblazer specifically the Fear and Loathing arc (http://www.amazon.com/John-Constantine-Hellblazer-Fear-Loathing/dp/1563892022).

It's from an American made Manga called Hellblazer.

It's pretty long and it's going to be very different from most Manga you've read. The American Manga scene is really different from other Manga scenes.

They're pretty different with similarities only being skin deep, but they're both pretty good.
