Salvia, in contrast, is consistently mind-clearing and grounding.
Then it is my turn to respectfully disagree. Have you not read the countless reports of people getting little more than confusion, disconcertion, anxiety, panic and even terror?
I think both these drugs are prone to extreme and unstable, chaotic or volatile experiences often happening at high velocity and using them via the smoked / vaporized route for a reliable therapeutic effect seems inappropriate, since the contrast of reliance and volatility is obvious.
Maybe it works for you, but I would not recommend it for this purpose because the chance is so big that it raises more questions than answers, or more disturbance than relief.
Another example of that is that DMT when smoked is a flash of a trip, very compact and jumbled. I have found meaningful experiences that way, but if a much more dilated form of the experience is used instead, like when taken orally activated or when taking an analogue that causes much more protracted effects (psilocin, or even more: 4-AcO-DMT) there is so much more time to take a good look at things and in a more stable - and reliable way - get therapeutic relief and/or spiritual catharsis.
In all these cases the dose should be limited. If the dose is too low, it can take longer for internal processes to proceed and for some things you need some momentum to break through barriers, but when the dose is too high it can not only defeat the purpose but also potentially cause more problems than that it solves.
What I must note though, is that I believe that part of the reason that Salvia causes so many chaotic and wild results is that people are just casually eyeballing it, maybe because of its innoccuous appearance. How many times are people just measuring in 'bowls'?
If you want to use Salvia for things like meditation or therapy I would investigate buccal administration or slow titration with smoking it, much more carefully than the average person is doing. If you want to get your ass kicked on a cosmic scale, that approach certainly works, but otherwise - for therapeutic benefit - not.
My opinion remains that there are many other choices of psychedelics that can be better for this, because they are less extreme.
