The second is better. If anything, the second is the only way to write a good addiction story. That said, a lot of my stories end up looking more like the first, because…I’m really, really bad at remembering to keep mentioning people’s addictions, and incorporating them into the story.
It’s terrible, really. I’ll give someone a cigar addiction, and then, a few thousand pages later, realize they haven’t smoked once since that initial puff. I tend to get carried away with other, more plot focused aspects of the story, and the smoking/drinking/etc. kind of falls by the wayside. I usually go back in and try and edit more instances of the addiction in, and that’s why the stories which are supposed to look like the later type actually end up looking like the former. I’m not a perfect writer, you see, and I just don’t have the time to edit all of these stories to the best they could be. People seem more interested in quantity over quality! I wish I could get these stories into perfect shape every time, but sometimes I fail, like everyone else.
