Perhaps, but "gascid" experiences will take you to that kind of awareness. It's not necessarily "fun", it permanently changes everything you think you know about "reality".
So in all seriousness don't do "gascid" unless you really, really are ready for some seriously life-altering shifts in perception of the reality around you.
Read Merry Prankster's post, it is worth knowing before you go down that path.
If you're gonna combo with nitrous, start smaller.
My first LSD experience was 320ug and two boxes of nitrous and it permanently changed me. I should write up a trip report sometime.
