Salvias open eye visuals are completely wholesale and otherworldly resembling where you actually are very little. With Dmt the rooms still there,for me anyway.  Salvia CEV i dont get any atall its strange. Only once i have on a low dose sober.   So yeah there are many differences. Also dmt is quite a centralised trip whereas salvia can pull you all over the place and is very dissociative. I find salvia rewarding and pleasant as long as im in the right frame of mind and beer goes well with it just not too much
