The Ohio Mound Builders smoked a type of local marijuana. Supposedly it very potent.
Not much has changed since the sixties in regards to those parks.
In college I was told that one of the caves in Europe contained evidence of cannabis use circa 30,000 BC.
That would be quite a trick since cannabis species are native to the old world....central Asia... And was introduced to North America by colonists, despite assorted hippie sites claiming prehistoric Indians used it.... The confusion may be due to totally unrelated plants like dogbane being called ‘hemp’ because they were as good for making cordage as true hemp.
This is probably the source of the confusion —

They did have intoxicating and hallucinogenic plants native to North America to use ...one is plain old Jimson weed. Before it showed up in the Mississippian [more recent than the Hopewell] archaeological record their art was tight and refined... After it turned up it became became disjointed and fixated on death symbols. I don’t think it was smoked, but might be wrong. I think it was taken orally. The Mississippians [the Natchez anyway] also used a kind of pill made of strong tobacco to render victims compliant before strangling them to accompany dead leaders into the afterlife.
