I've been told this in 2 different states now and they're saying the same shit. They're both in the deep south though so they could've passed similar laws.
FWIW, if I had to choose something for acute pain and taking euphoria out of the equation, I think Fent is the best pain killer. At least for short term acute pain.
Not sure I'd use it for a migraine though because they seem to be different than other types of pain and Fent gives me a headache sometimes so I'd probably choose a good shot of Dilaudid or even a double dose of Demerol for a migraine. No matter my tolerance, if I'm not sick, a shot of Demerol and Phenergan usually knocks a migraine dead in it's tracks but I usually try to take a few lortabs or percocets too. IMO, relief from a really bad migraine > a great IV rush and buzz.
