Sounds a lot like cognitive bias to me. It's ultimately a placebo if you still need to put the work in.If you take a doping pill to run faster, you still need to train and to expand heavy personal effort during the race. Is the doping pill "placebo"?
Heck, if you have leg surgery after an accident, depending on the type of surgery, you often need (and are advised by the doctor, and asked to take it up with physiotherapist and such) to put in personal work and exercize properly for months, to be able to walk and regain use of your leg again. Is the leg surgery placebo?
Or how about a debugger. It wont solve your problem automatically. You still need to write the program yourself, to look into different places, and to know how to find a bug etc. Is the debugger a placebo?
Needing to put personal work to get a result is not what's the distinction between a placebo and a drug.
A placebo is not that which is only effective when combined with additional personal effort (that can hold for any regular drug).
A placebo is a neutral drug that does nothing at all itself (it's just water, or some neutral powder or saline solution, etc) and it's effectiveness is all about the belief that it helps.
Besides, psychedelics (even assuming what they do have no bearing at all to getting better from depression, etc, an assumption with which research disagrees), have huge immediate effects on mental state when taken. So they're not neutral in the way a placebo is even on that account.
