DEA, THC, and Abbot Laboratories

Marijuana is illegal specifically because of THC (because it gets you high). Marinol is synthetic THC (Marinol is owned by medical giant Abbot Laboratories). Marinol is officially approved by the DEA for providing a safe, ingesting in pill form rather than smoking, method of consuming THC; you know, like, "opium, which are (is) sold as pharmaceutical products like morphine, codeine, hydrocodone, or oxycodone".

So how the DEA contends that there is no medical value from the marijuana plant, when the DEA itself states, "The active ingredient of Marinol is synthetic THC, which has been found to relieve the nausea and vomiting associated with chemotherapy for cancer patients and to assist with loss of appetite with AIDS patients" is absolutely mystifying.

Is it possible for synthetic THC to possess medicinal qualities if natural THC does not also possess such qualities?

And there is no lawyer in this nation capable of pointing this out?

I don't understand . . .
