^If it tasted sweet, it was not salvia. I'm sorry- you DID NOT take salvia divinorum. It doesn not have the effects you described, you need way more then you took, it is not a sugar substitute (which Stevia can be), it is bitter (stevia is SWEET), you have to chew the leaves for half an hour or so, and some person would not have given it to you. There is no reason at all that is was salvia divinorum; so you checked wiki? But nothing you did or described about the plant is remotely like salvia....
You have simply made an error- it pretty clear that you have mistaken the word Stevia for Salvia. Its not a big deal- its just annoying that you won't stop with this nonsense. But feel free to keep up the illusion; I just hope that nobody reading it believes you, because it is not true. Please educate yourself before saying incorrect things.
I grew salvia for a while; its is an odd plant thats for sure, and hard to grow in Australia. Its is native to one small region of the world in Mexico, and if the stories are true, existed in only to gardens in that region. Most, if not all, salvia plants come from one cutting taken during the 1960's; there is little variaton in the species that I've seen. The leaves have a very odd dull shimmer to them, and the stems are square and hollow...
