The effect of the USDA rules in 2020 is going to depend on two things:
1.How much they are willing to incorporate the huge number of comments they have received and,
2. The level of actual enforcement they are capable of overseeing.
At this point I would encourage farmers to assume that Total THC of .3% will remain in the rules but given the lack of testing infrastructure, I do not see how they are going to successfully test all farmers in the limited timeframe using DEA Certified testing facilities.
