WWII: TOBACCO SENT TO THE POWS?

THIS QUESTION IS RE-POSTED, BECAUSE SOMEBODY NAMED CHARLIE, WHO DOESNT HAVE ALL HIS FACTS, SAID TO ME: "SOMEBODY IS PULLING YOUR LEG." NO: CHARLIE, SOMEBODY IS NOT PULLING MY LEG. I AM A COLLECTOR OF WAR LETTERS, WAR PHOTOS, AND MISC DOENTS. MY QUESTION IS: WHY DID THE GERMAN GOVERNMENT BAN TOBACCO FROM NEXT-OF-KIN CARE PACKAGES SENT TO THE POWS? ...WHAT I LEARNED IS: OUR US GOVERNMENT ISSUED PRE-PRINTED MAILING LABELS TO THE FAMILIES, WHO THEN SENT THE MAILING LABELS WITH THEIR TOBACCO ORDERS TO THE PARTICIPATING TOBACCO COMPANIES, WHO MAILED THE TOBACCO DIRECTLY TO THE POWS. I HAVE DOENTS THAT PROVE THIS: MY COLLECTION OF WAR CORRESPONDENCE INCLUDES MATERIALS FROM THE FAMILY OF AN AIRMAN WHO PARACHUTED INTO SWITZERLAND: THERES A FOUR PAGE CATALOG, ISSUED BY THE GOVERNMENT, OF TOBACCO PRODUCTS THAT THE FAMILY COULD ORDER. AND I HAVE THREE MAILING LABELS THAT THE GOVERNMENT SENT TO THE FAMILY.
