This reads a lot like a story and I think it really helps get the point across.
I like how in the beginning you don't exactly say what it is, the addiction. You list the addicting qualities and paint it out to be quite bad and it really sets up the rest of the poem/story.
Then I like the way you work it into a personal story. It really enhances the idea that it is bad because you give an experience that you've been through and really tie in all of those previously said bad parts of doing it, add a story and it works nicely.
My favorite lines:
"But I guess things have to get really bad
For you to realize how much you need help."
^^^ so true and it also fits nicely into the theme. You can't see the light until you're in the dark. It doesn't seem as important. But it also shows how strong you are to be able to notice that you need help and to want that help.
