I smoke weed quite a bit and that is nice, but weed and salvia aren't things you should compare.
Salvia is an intense dissociative hallucinogenic, you lose touch with your current self and you go through ego death. Which sounds bad but is pretty god damn weird. I am not gonna say it is awesome at all points. It is quite an experience though, definitely not meant to be social. You should have a sitter [Someone sober to watch you] Your first couple of times, and you should direct them not to talk to you at all because it interrupts the experience.
I followed this guide
https://www.sagewisdom.org/usersguide.html and had a good time. Take care with le drug though.. also mixing weed and salvia is also a nice thing. Salvia still gonna take over though.
