Yes, Chewing! :: BLACKBLACK Gum Fanlisting

What is a fanlisting?
A fanlisting is a place for all the fans of a particular show, movie, actor/actress, singer, etc. to come together and build the biggest listing of people all around the world who are fans of that subject. In this case, the subject is BLACKBLACK chewing gum. We are the official TheFanlistings.org fanlisting for BLACKBLACK.

What is BLACKBLACK?
BLACKBLACK is hi-technical gum from Japanese candy-maker LOTTE.
Exactly what 'hi-technical' means continues to elude us. What we do know is that BLACKBLACK is jam-packed with caffiene and wrapped in a tidy little package. Targeted to hard-working men who need a little pick-me-up, BLACKBLACK tastes like a mix of black licorice and menthol cough syrup. We've heard that it also contains nicotine, but we've been unable to substantiate this claim.

I have been told by asian grocery store operators in San Jose, CA that area police officers love this stuff.

Where can I buy BLACKBLACK?
If you live in a large-ish city, you should be able to find a Japanese (or asian) grocery store. If they carry candies or chewing gum, you will most likely find BLACKBLACK there. If not, there are several online distributors. DISCLAIMER: I am in no way affiliated with the online shops mentioned. I receive no kickbacks whatsoever for mentioning their sites. They are listed as a convenience to the reader.
ThinkGeek.com carries BLACKBLACK, and their prices are very reasonable. (They also have the excellent Bawls energy drink)
PCMods.com also carries BLACKBLACK (oddly enough).
jbox.com is another Japanese snack store.
And of course you can always use your favorite search engine to find a store.
