These are just growing pains. With the passage of the Farm Bill, hemp and hemp products to include CBD are legal now that hemp has been taken completely off the drug schedule, in fact it is no longer a drug at all.
States now have to catch up with the new law of the land and reality that hemp is no longer a schedule 1 drug and they are doing just that all across the land. This is exactly why William Barr said, in his hearings to be Attorney General, that the Federal government and the States need to be in agreement regarding cannabis and that he would work towards that end. He also said that he supports states rights regarding cannabis and the will of the people.
Where the Federal government was out of step with the states regarding cannabis, now that hemp is legal at the federal level, the states are now out of step with the federal government and are playing catch-up and will have to change their laws to reflect accordingly. For instance, the Idaho state patrol just confiscated a truck load of hemp certified below the legal limit for THC. The company even had all the proper paperwork but Idaho still confiscated because Hemp is illegal in Idaho. This case is the courts now and will be sorted out but in the man time they don't even seem to care that the hemp may mold as the courts resolve this legal issue and the hemp is worth more than a million bucks...
