OK, first off, STD is a Sexually Transmitted Disease. I have it on good authority that although some pipe smokers have STD's. STD's do not cause pipe smoking. That's a fact. You can look it up.
STG is the Scandinavian Tobacco Group. They are the largest producer, distributor and retailer of pipes and pipe tobacco in the world. They produce a large number of brands under license. Over the past couple of years, they have been trimming the number of SKU's and discontinuing underperforming brands. Also, some licensees (such as Dunhill) have opted out of the pipe tobacco licensing business due to a lack of profitability. I was a partner in a company that did just that a few years back, selling our brand trademarks to CI.
Word of advice: If you post about some "secret" information that "some guy" told you, expect a lot of push back from the knowledgeable membership here. Facts matter, and if you don't have them, don't pretend that you do.
