No medical background here, but I've had that same thought myself.

I know it's completely unethical to prescribe a placebo (and I assume knowing it is a placebo erases said effects) but how nice would it be to have the ability to experience some relief without the cost and side effects of a real medication!

If you believe in the placebo effect, it can still work even if you know you're taking a placebo. https://www.psychologytoday.com/blog/all-about-addiction/201...

It's unethical, but in France they do it all the time -- it's called homeopathy.
