Cannabis doesn't have thorns, though. I suppose if you go trampling through a field of some dank sensi, thorns might stick to you more easily, lol. But, cannabis can be eaten as a food: you can use the trichomes and mix them with fats, oils, or alcohol to consume for medicine, or you could eat the seeds, as food. I guess you could make a salad out of fan leaves, too. All that said, I think cannabis was before the fall. As for the fall itself, I see it as them being awakened to a higher consciousness, a new awareness of God, and of themselves, and the world, and stuff. God knew they couldn't handle that kind of consciousness on a constant thing, so he banished them, and made them work in order to get that awareness rather than given, in the Garden. Weird, yeah, but a part of some consciousness-bending, mind-warping stuff I was pondering on while enjoying the fruits of my first ever crop.
