I'd think it goes the other way too. I've worked in a lab as a data entry helper for studies of opiods on different tissues. They had no problem getting funding for their studies. I would imagine it was because it was related to War On Drugs. So there was an element of "let's show the world how terrible these drugs are, here is some money".
Experiments used fentanyl and naloxone. Aside from keeping fenanyl locked and logging/auditing its usage and waste, don't remember professors or grad students complaining about it being hard to study.
