No, the Lancet did not “reported that fluoride is a Neurotoxin in the same category as mercury, lead, and arsenic”.  It simply published an article in which the authors, Grandjean and Landrigan,  briefly expressed their opinion that fluoride is an environmental neurotoxin.

The Lancet also published a subsequent article in July, 2014 which pointed out the fact that this  opinion of Grandjean and Landrigan was based solely on Chinese studies which were so flawed as to render them of no relevance or credibility.
