The abundance of pseudo scientific studies that; Confuse correlation with causation. Fail to control for anything to get an interesting conclusion. Or just exaggerate the results. Has left me to instinctively assume, just from the title that either; Cancer causes alcohol use. Alcohol use causes smoking. Or their sampling groups is in a cancer ward.

I'm not saying this is a bad study, or article. I'm just commenting on the sheer amount of crap circulating is leading to a general skepticism that seems to be filtering out people like me from even clicking the title/link to these studies.
