It goes far beyond smells, in ways I find deeply unsettling

We can induce religious experience, see "The God Helmet"

https://en.wikipedia.org/wiki/God_helmet

or deep depression & suicidal thoughts

The Wikipedia page seems to show that it's just a placebo/scam? The helmet has the equivalent magnetic effect of a fridge magnet or hair dryer, and researchers in Sweden replicating the research in a double-blind study found no effect at all. Looking at the pictures on the official website https://www.god-helmet.com/wp/god-helmet/index.htm , it's just magnets on a snowmobile helmet this guy bought.

That god helmet article seems to thoroughly debunk it as snake oil quackery, which is indeed deeply disturbing

Thhe "God helmet" was likely a placebo device. From the very same Wikipedia article you linked:

> Other groups have subsequently found that individual differences such as strong belief in the paranormal and magical ideation predict some alterations in consciousness and reported "exceptional experiences" when Persinger et al's experimental set-up and procedure are reproduced, but with a sham "God helmet" that is completely inert or a helmet that is turned off.
