One thing that stands out is the position that Congress should wait until more states decriminalize marijuana before they take action to reschedule.
What is striking about this and makes no sense is that the same government that classifies marijuana as Schedule 1 (no medical purpose) has issued numerous patents for the medical use of cannibinoids/cannabis (dating back to the 1980's) through the United States Patent and Trademark Office including one patent issued to another U.S. government agency, Health and Human Services.
US Patent 6630507 states in its abstract in no uncertain terms that cannabis does have medical applications. There are 29 single spaced pages of medical science behind the patent application which was granted including cites to other medical cannabis related patents.
The Abstract is pretty clear on the medical use of cannabis:
"Cannabinoids have been found to have antioxidant properties, unrelated to NMDA receptor antagonism. This new found property makes cannabinoids useful in the treatment and prophylaxis of wide variety of oxidation associated diseases, such as ischemic, age-related, inflammatory and autoimmune diseases. The cannabinoids are found to have particular application as neuroprotectants, for example in limiting neurological damage following ischemic insults, such as stroke and trauma, or in the treatment of neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease and HIV
So in the end, why is it again that Congress must await state action on decriminalization for rescheduling of marijuana to reflect well-established science. But then again, the same question might be asked on any number of science based realities such as climate change against which Congress rebels.
