(rather poor) Translation from German by Google 
I searched Google for "BfR rät vom Konsum der Kräutermischung", the title of this link, and hit the Translate button. I invite you too do so also, and confirm that the word 'tobacco' is not to be found anywhere in the article. Near the end of the PDF is this statement: "Information on potential risk can not presently be made". Both statements about Spice and tobacco which this citation purports to verify will now be removed, and should not be restored other than in the unlikely event that citations for them can be found. Liars Busted. I will now look at the edit history to find who added this willfully erroneous information.
