But were they pot smokers alone, without the hashish?
Whatever your answer, how can you prove it? They grew it. Do you think they didn't know that it could also get them high? They grew, dried and smoked tobacco. They could do the same with hemp. They could even mix it with their tobacco to get an appropriate, controlled high, as had been done for thousands of years by mixing weed with other plants. Did they not know about this, or that weed was also used medicinally (and still is, BTW)? Why not?
First, if America was a cannabis using bunch of pot heads in the 1700s led by the founders and heroes of this nation, then they would use the product freely, and with familiarity, they would grow great pot and make and use hashish, they would sell it, party with with, write about it, there would have been a booming pot trade and pot shops, and pot would be immensely popular in America and and for centuries, with no break from then until now.
Instead there is zero reason to think that your lies are anything but lies.
