You can't really trip per se. But theres an extent where you have an increased and out of ordinary state of mind, seeing and hearing in a very different way. colors and sounds seem brighter. I smoke oil that is 98% thc that i make at my work's Lab, and yes the first time i over did that, given i smoke every day all day, its pretty much my job, i felt like iwas hallucinating, and my perception was really off in a bad way. I actualy got paranoid and behaved very akwardly towards strangers. now i know that at a point i have to cut myself off on the co2 extract, or else i'll get that high again. you really can't get that much higher, it just gets more uncomfortable from them on. But I mean i grow about 60 different strains and have tried thc in almost every way possible, and with my tolerance being so high now sometimes ill smoke a bowl of hash and hardly feel high, so your lower tolerance helps get to that state. also a friend who doesnt smoke anymore ate one of my edibles and almost had the same feeling of being tripping as he put it. but its nothing like tripping of psychedelics, or even something like robotussin. you can't really call it tripping if you've tried really things that make you trip.
what do you mean by finding shrooms? like buying or picking?
