What do you think about the new study regarding Niacin?

On GMA they just talked about a new study of people with previous cardiac disease, and it says taking large doses of Niacin is dangerous. Side effects like diabetes, infection, bleeding, and does not reduce incidents of heart attacks or stroke, but did reduce bad LDL cholesterol and raised good cholesterol HDL. You might know that I have always believed you can “OD” on B vitamins and other water soluble vitamins, but this study does have me questioning whether the company that funded the study is happy with the result or not? Merck conducted the study, so did they want to promote their cholesterol drug, or were they interested in making a new drug with B3 in it? My guess is the former. All these studies are a nightmare when you start picking them apart.

Edit: It seems Merck was testing a niacin drug they made that also has an anti-flushing property so who is to know if it is the anti-flushing drug is the actual real problem. http://www.medicalnewstoday.com/articles/257472.php
