alt Hacker NewsThis is mostly incorrect. The DEA enforces the Controlled Substances Act and the list of scheduled drugs, not FDA regulations.
If you are out there using e.g some experimental cancer drug that hasn't been FDA approved yet, the DEA isn't going to stop you. Their mission is to stop recreational use of drugs that get you high.
FDA approval and regulation is how you end up with a legally dispensed controlled substance of a prescription. If you manage to get the controlled substances from a non-FDA approved source what you have is a pile of illegal controlled substances.
They are not going to give a shit about most experimental cancer drugs because they're not controlled substances.
