Sativa-dominant strains have psychedelic qualities, offering dramatic introspective, frame-shifting experience. It isn't as profound an experience as one from psilocybin, but that's not necessarily a bad thing. I've experienced realizations while under the influence of sativa dominant strains similar to, if not greater than, those uncovered during therapy with a psychologist. However, other times the re-framing of reality was simply fiction or not as epic as what it felt like while under the influence. Since the experience is so introspective for me, I partake in it sparingly, in the right settings where I can get the most medicinal value from it.
