I was a bit iffy about whether butts are evidence of humans or not, as well. I think the Tobacco (Nicotiana tabacum) flowers are pretty, especially some of the cultivated varieties. For example, searching cultivated shows a few chocolate-colored ones.
Maybe someone could grow their own and make a cigar/cigarillo? I’d agree with it as being the plant if they had growing, flowering, drying, rolling, etc. pictured in the observation.
