Wanna try salvia but dunno how

For context I’ve been smoking weed consecutively for 2 years and while, I love weed so much, I’ve always been curious about psychedelics. Last year I tried shrooms with some friends but instead of feeling a life changing experience I just saw some cool colors/visuals, but nothing I read about. I wanna life changing experience or at least something that can dive deep into my mind at first I became obsessed with trying to get my hands on datura but my girlfriend was heavily against it, but I’ve read saliva trips that seem like I can handle and saliva doesn’t seem like it last as long as datura. My only problem is I don’t know how to get my hands on it (without getting scammed online) or even how to smoke it. Anyone can let me know anything I would say im still very much a beginner looking for a more intermediate experience.
