No? Tobacco companies themselves knew tobacco wasn't harmless. Just like oil companies have known for almost a century that humans were causing drastic climate change due to CO2.

I don't think tobacco companies knew 100 years ago. The data didn't really become conclusive until something like the 50s. There absolutely was a consensus in the 20s and 30s that cigarettes were not harmful.
