Sorry, I'm really high right now and either came up with the best or worst idea ever... Lets say hundreds of thousands of avid Marijuana fans fed wild birds with lots and lots of Marijuana seeds in bird feeders everywhere in the world. Would these birds then fly around, digest, and excrete (fertilizing) the seeds - which would eventually adapt like everything else wild in the world that learns to adapt in nature? If this could happen.. these plants would learn to grow everywhere in the world and would become so big that the government would have to accept Hemp and Marijuana as part of our culture and eventually in the future it could become our National Plant wrote about in history books.
wild hemp grows all over the mid western states and its not making anymore progress or any less.. Marijuana growers that operate independently but closely to each-other, in cluster, often contaminate other growers crops. due to neglect or laziness to remove male marijuana plant.. marijuana is more related to corn than it is dandelions .. it cant grow wild like that.. while it can to some extent, it need assistance and cultivation like corn
