I've had several shoulder surgeries and was prescribed both oxy- and hydro-codone. I experienced the itching, but it worked great, and the OTC pain relievers did nothing. I still suffer, in fact; I never became addicted - once it ran out I tried all the non-opiate alternatives the doctor prescribed. None of them worked. I live in pain every day, but most days are completely bearable. When I do feel pain, the other medications don't help. I know that if I work out or do yard work or something, I can take the non-opiates and stave off the terrible pain I would feel hours later, but when I already have pain they are ineffective. I haven't had any of the "strong" stuff in over a year and a half... and yet, if I mention that the other drugs don't help to my doctor, it's obvious to me he thinks I'm pill shopping.
I mention it because the biggest complaint I see against this over-the-top, for-your-own-good regulation is that the people who are actually in pain are treated like criminals and often denied medications that would make life more bearable. I admit I've managed without, so I'm not including me in that list... but I understand the position completely.
Frankly, even before my surgeries, I never agreed with the war on drugs; I do not agree with vice laws in general.
