Yes, it can be done.
Consider: the DEA classifies marijuana as a Schedule 1 drug, with “no currently accepted medical use.”
But they allow their buddies at Insys to produce synthetic marijuana and classify that as a Schedule 2 drug, which is legal.
How much money passed hands for that to happen?
Did I mention Insys also illegally marketed Fentanyl, the opioid drug that has become a scourge to America?
With a track record like that, how could the DEA refuse them?
