I've smoked what people call "ditch weed" And I got so ripped off of it I had to set the controller down for a sec. But I think It had a lot to do with I under estimated it. I'm not saying it was good shit or anything but It got me high for sure, but like I said before, it just didn't last very long. Did that shit you found have trichs all over it?...If so I would say it would be worth your time....I probably shouldn't say this but years ago before I decided to grow quality herb, I did experiments with the wild stuff every summer. I learned a lot about marijuana that way, I just couldn't bare to believe such a beautiful plant was "ditch weed" I discovered by eliminating all the males, the females produced very large colas exploding with pistols and a fair amount of them showed beautiful pink pistols. one year I picked about 6 oz's off one plant (not even the whole plant) to check it out and it wasn't half bad. It physically looked like dank bud but had the qualities of mids. If I didn't have all the quality herb I have today I would totally be getting in on that shit. But like I said before and I'll say once more, I think indeed what I have here was grown for hemp purposes way back in the day, but over decades of time the genetics have bumped up, quite a bit in some cases. Just look for the ones that are the most dense with trichs, so what if you get a few beans. In your case with no males around you may not have "a head of seed" give it a shot I say!
