From what I’m reading the general consensus is symptoms of higher serotonin or a higher concentration of G proteins making the existing serotonin feel stronger.
Personally I’ve found some dabs and weed has made me feel serotonin levels in my body more than usual. If I’m only getting more sensitive to the existing serotonin thanks to G proteins that would make sense for weed not being addictive chemically.
I consider microdose of shrooms level to be trippy. Where I’m thinking like I would on shrooms or acid. As far as visuals I just get the occasional fractal when I close my eyes. Not really anymore than I get when I’m hyped up.
Yes for keen eyes I do get natural fractals when hyperactive. It could be relevant in trippy weed experiences to those of us who have found some weed to be trippy.
The study i linked to went into a lot of details about the effects on 5ht receptors.
The cliffnotes version is essentially thc doesn’t increase serotonin. It affects G proteins to regulate serotonin function rather than add more of it into body chemistry. It increases sensitivity to serotonin.
Cbd as we likely all suspected does work on reducing serotonin sensitivity by working on G proteins in an opposite manner to thc.
The study despite testing on rats used the scientific method. It looks to be a baby step study towards testing on humans. Though the exact method can’t be done the same way on us as we likely wouldn’t want our brains Removed after severing the brain stem while alive and without anesthesia.
We’d likely have a way to test for all of this without brain surgery for testing. I’d expect a blood test or something in the same aspect of noninvasive internal testing.
