I like the ending of this piece :) However, allow me to give my feedback on some things..

"Either way he the nicotine addiction is going to be his end."
^ Did you mean this nicotine addiction? It's a bit vague and I didn't really understand this line.

"and it about killed you to watch him go into withdraw"
^I think you meant "it almost killed you". I also think it should be "withdrawal" not withdraw.

"you could of fought harder"
^could have.

"when he quite the first time"
^should be "quit".

"deal with the withdraws and jerk like tendencies"
^Another "withdrawal". Also, should be "jerk-like", as far as I know.

"Your feel about has flawed has the nicotine itself, harmful yet seemingly helpful"
^I don't understand this line at all :/ Mind elaborating a bit?

"and your standing in Church has some priest"
^This is also quite unclear, but you should replace your with "you're" :)

"but your really relieved the fights over"
^Another "you're", and "fights" should be "fight is/fight's".

"your get in your small hybrid car"
^Should be "you".

Allow me to also make a few comments on the piece itself:
I think it lacks too many full stops and commas, some lines were too long I could barely take a breath to finish them. It made the whole piece quite off flow.

Also, Try to separate the paragraphs to make stops between the several thoughts in the piece. Like, right now it's one big piece without any paragraphs that separate it to make it look and sound full of scenes, and so it looks like someone is just pouring out some thoughts, readers will be a bit intimidated when they see the whole piece like this.

I hope you forgive me for this scrutiny, I just want to pour out an honest opinion and not just complement :)

Write on~

I actually liked the form you have here. I don't think it's necessarily considered prose or anything, but it has a few poetic devices in it. I really loved reading and the message is indeed clear. I too stumbled over a few things, but I knew what you meant. After reading it makes me wonder if this was close to home for you, seems as it may be? Interesting piece, worth the read.
