Quack Dr Rodu?

So I am on youtube and saw a dude "chew" 5 cans of chew at once and went to his main channel and saw him having an interview with a Dr. Rodu who says that smokeless tobacco is not dangerous. Does anyone have any info on him like any actual scientific journals and studies and such? He sounds quacky to me. But here is the video. I would like your thoughts.
