As said earlier, the new interim rule by the DEA implicates many of the regular hemp processing activities under the Controlled Substances Act. The interim rule by the DEA explains that cannabis-derived materials must not have more than 0.3% of delta-9-tetrahydrocannabinol by dry weight. It is common knowledge already that the delta-9-tetrahydrocannabinol level in hemp is far lesser than that of marijuana which is covered under the Controlled Substance Act.
