Maybe in the 70s. I haven't had less than a pound (several different strains) or so in ages.
I know that wild hemp you talk of. As you leave downtown here and go north, you would go past big stands of Christmas trees.
First time I saw it around here was 4 wheeling when I first got here. Found ourselves in a big field of budding Christmas trees.
Didn't smell killer, and you could smoke a joint 3 feet long and just get a sore throat.
Apparently they grew a ton of hemp around here in the WW2 days, and it still is in pockets here and there.
In the American Journal of chemistry I found info where similar pot from Minnesota was extracted with alcohol, then isomerized, ending up with strong oil. Off I went to buy an isomerizer.
Things have moved along quite a bit since then.
