I don't know if that statement is 100% valid.
A lot of the homepathic/accupuncture/etc. utilize the placebo effect. As we all know (or should known) the placebo effect isn't just physiological but can have positive biological effects too. So the question is....are we ok with the masses paying money to feel better/get better even if it is only the placebo effect? If people feel better after having tiny needles put into their skin...if it doesn't cause harm why not let them do it?
We should not let them try it because, placebo or not, it does hurt people. It hurts people because:
1) Robbing someone is a harm. One of the reasons we regulate drugs is that desperate patients will try anything to make the pain to away, or to make the prognosis a little less hopeless. We know we need to protect them, or more accurately to protect our future selves, from becoming bankrupt in a futile attempt to fix the unfixable.
2) Degrading people's faith in science is a harm. Chiropractors are a gateway drug to superstition. They hook you when you are at your weakest and, if you feel the slightest relief from their treatments, they lead you into the belief that everything you've learned about medicine, biology, and (in the case of acupuncture/homeopathy) even physics is a lie or at best a competing theory with what they're selling. That weakened understanding of science eventually manifests as vaccine refusal, chemotherapy refusal, or any one of a dozen other life threatening pieces of ignorance.
3) Reinforcing neuroses is a harm. We know that many of these quacks' customers, like many of our own patients, actually have few if any real impairments. Yet they are impaired... by the idea that they are impaired. Reinforcing that denies them whatever hope they have to break free of role of 'the patient' and go back to being a person
4) Denying someone the chance to accept their infirmity is a harm. Even if the illness is real, that doesn't mean its ok for the cure to be fake. This is why we stopped prescribing placebos in the first place. Doctors used to do that, back when it was 'harmless', everyone carried a big bag of blue chalk and, if you couldn't cure what the patient had, you mixed the chalk in water and gave it to them for the placebo affect. But we realized that this was denying our patients something very important: the chance to grieve, and ultimately accept, their own illnesses, infirmities, and even their impending mortality. The truth can be painful, but we know from long experience that an accepted truth is never as awful as a protracted lie. Everyone in medicine has seen patients live their life, fully, despite pain or disability. We've seen people make the most of the last few months before their deaths. And we've all seen patients with incurable conditions hobble from physician to physician, trying one experimental treatment after another, allowing their conditions to consume the life they have left, allowing the patient in them to eat the person. Maybe that's ok when there's hope for the treatment, but if you know you're handing out placebos its just a tragedy.
There's very little nobility left in medicine. We don't generally risk our lives anymore by going to the hospital, we rarely have to face down plagues and when we do we've gotten very good at not catching them. We do good work, sometimes, but curing someone with a curable condition isn't noble, it just common decency. Its like giving water to a man dying of thirst, and getting paid for the water besides. However there is one single noble moment left in medicine: its when you look at a patient and tell them 'I'm sorry, there's nothing I can do'. Its a moment with no profit in it, no thanks, and no glory. Just a lot of humanity, and a lot of good.
F- anyone who gets in the way of that by offering a bag of placebo. If they charge $100/visit for that placebo f- them twice.
