I am not saying that medications aren't over prescribed or inappropriately prescribed. We, definitely, have a problem with prescription drug abuse in this country, and, yes, some doctors are unscrupulous and only care about the money.
What I am saying is that it is unfair and wrong to "blame" a doctor for someone's addiction. A doctor who is seeing someone for whatever condition has no idea that any one person has any greater of a chance of becoming an addict. There is also no saying that that person would not have become an addict anyway. Maybe that oxycodone after a root canal, or that 0.25 of xanax to use as needed until the SSRI kicked in did start them on the death spiral, but there is no way to say that it wouldn't have happened anyway.
Yes, if a doctor knows of a patient's history of addiction then, unless there is no other alternative, it is inappropriate to prescribe them a narcotic, but if a doctor doesn't know of a patient's history or if the patient has no history of drug abuse then prescribing these medications may be appropriate.
As an aside, and interestingly since you mention Florida, Florida was one of the states that had the biggest problems with "pill mills" being, mostly, pain management clinics that prescribed opiate pain medications with little oversight. A few years back they had a dramatic uptick of prescription drug overdoses they overhauled their system and now Florida is, actually, one of the more difficult states to get long term narcotic pain medications.
Many states are now using prescription drug databases (I live in NJ, I know that it is used here) in which doctors can look up what medications were prescribed, when, and by whom. The problem that exists right now, though, is it is a state-to-state thing. So, even though I live less than 15 minutes from a bordering state, you can only see the prescriptions filled in that state. So, if, for instance, someone has a very long history of prescription drug abuse in NJ then can pick up and move to another state and there is no record of them ever having filled a prescription.
My issue is with "blame." It is easy to blame and put the anger off on someone else, but the truth of the matter is that addicts choose to be addicts and remain addicts. If someone wants to maintain their sobriety they are honest with their healthcare providers about their history, they refuse narcotics if offered. They don't take advantage of the situation.
I have a co-worker whose father was a recovering alcoholic. He was so serious about his recovery that he refused narcotic pain medication even when he was dying of cancer. He told his family, "I f@#^*! up a lot of years, I intend to go out of this world as a sober man."
