Can anyone recommend quit smoking resources in German language?

Trying to quit smoking with my husband, but he despises reading english lol. So I am looking for websites, online cessation programs or books suggestions, for printed materials in German.

Must be German language * thanks*
Thanks for the wonderful information guys. I am in Germany, I am just learning the language so I am not so proficient at searching or navigating german sites. I will give my husband the links and have him order them.
