Since a few months I experiment with vaporizing plain Salvia Leaves in my SSV. I found these leaves to be a very powerful antidepressant and had mild trips when I combined a small amount (~0,05g) with cannabis where I would see a lot of fractals and had a few visions of entities.
Without Cannabis I feel I need to up the dosage a bit more (~0,10g) to get comparable effects.
I always start by taking one big whip hit and keep the vapor for about 20-30 seconds in my mouth and wait for the effects.
However since I do not know much about the effects of higher dosages of vaped Salvia I am a bit anxious to take several deep whip draws back to back.
I find the dosage to be much more controllable when Salvia is vaped as opposed to smoked because the effects come on much slower and build gradually. The comeup feels always a bit rough for me but after I reached a plateau I feel more confidence to travel deeper until I reach the visionary level.
When I take a hit of plain leaves of Salvia I also typically feel inspired to draw or write since I feel connected to the psychedelic realm without losing coordination.

What are your experiences with vaporizing Salvia leaves?

I never used a vape with it, but when I used to live in a region where they could easily be grown outdoors, I had extremely happy, healthy plants with leaves that where hairy and had the most lovely velvety sheen to them. The leaves by themselves were very visually hallucinogenic as well as producing a positive perceptual shift. It was intense but it could be channeled into meditation etc. Everyone who tried them preferred it to the extracts.
