Gee that is a pretty good observation. Like no kidding. Of course that would be the case, but hemp is a huge product and you would have to get them out from under the Schedule 1 designation. Oh, and by your reasoning marijuana in any form would make those patents we have useless.
There have been several McConnell proposals in the House to decriminalize marijuana and they have died a quick death. Hemp?? Half the people in the country will think it was a quarterback who played for the Buffalo Bills.
Do you think Kentucky farmers would be interested in planting and selling hemp with no THC and other alkaloids?
Hemp is defined, at least loosely, in Canada as a plant having less than 0.3% THC. That has to be enforced somehow, otherwise you're raising marijuana instead! Even in Canada where growing hemp is legal there are controls. How much easier to control that nobody cheats and grows cheap weed under the guise of hemp if we are able to certify that THE CROP VARIETY in question is guaranteed 0% THC thanks to an XXII patent.
By the way, do we have patents on hemp varieties etc created similarly to our tobacco patents or are we just engaged in initial research?
Finally, wild hemp ranges between only about 0.3% – 1.5% THC.
