Christopher Jones If King was still taking hard drugs he'd probably be dead right now, from one overdose complication or another. I don't know about you but I prefer a living King to a dead one.
a. The phrasing of your question seems like you don't really want an answer, but to make a point that you dislike Stephen King... Having said that, this is not at all one of his best. We can never truly know what books were written during what period. Who knows if he's truthful about it. Addicts can be hard to trust.
Mike Marsbergen He's got good stuff from both eras. This one was written while he was healing after being hit by a van, and he was addicted to OxyContin at the time.
Teresa I may not be the best to answer this, but I like the majority of his work, whether it was written during his addiction or his sobriety. However I do think that some of his older work is a bit darker, which may be attributed to his addiction, setting as how addiction/alcoholism can cause depression.
