Forum:One Piece: Collection

Hello!

I've been a fan of One Piece for some years now and I've decided that I want to buy my own copies of one piece dvd's and manga volumes. After searching around for a bit I found this:

http://www.amazon.com/One-Piece-Collection-Colleen-Clinkenbeard/dp/B004W75BQU/ref=sr_1_1?s=dvd&ie=UTF8&qid=1323132584&sr=1-1

But I worry because I heard the episodes displayed on the US suffered, well, some change... like Sanji's cigarettes becoming lollipops and things like that. I wanted to know if the episodes in this collection are = to the ones they show in japan.

Thanks in advance and sorry for any mistakes, english is not my first language.
