Section 8) Related or Precursor Chemicals

DEA maintains that the presence of numerous cannabinoid substances in marijuana makes it impossible to generalize about marijuana on the basis of cannabinoid research, and that marijuana and its constituent parts are more dangerous to use than THC, the principle psychoactive ingredient in marijuana.

Modern research firmly establishes the interrelationship of the cannabinoid family of chemicals unique to marijuana, bound together both by chemical similarity and by a common mechanism of action in the human body.

There are no significant reports of abuse of the synthetic THC pill approved by the DEA in the late 1980's for nausea associated with chemotherapy.

Modern cannabinoid research, including research on marijuana, is based on the validity of assertions based on scientific research on marijuana's separate cannabinoid constituents.

DEA is not authorized under the Controlled Substances Act to make scientific or medical determinations, and must accept the paradigms and conventions of the scientific community.

The scientific community recognizes the treatment of cannabinoids as a group for classification purposes. This relationship is explicit in all cannabinoid research, and is the basis for the development of new therapeutic drugs.

There is no scientific basis for an assertion that marijuana had a greater dependence liability than D9-THC.

There is no scientific basis for an assertion that any cannabinoid compound has a greater dependence liability than D9-THC.

There is no basis for distinguishing between the scheduling of marijuana, cannabinoids, and D9-THC on the basis of dependence liability or potential for abuse.
