Very, very different. DOM is a one of a kind substance I feel like. From the substances I've tried it feels closest to 2C-E, Mescaline and TMA-2. It has that forceful, analytical headspace of 2C-E although its less sharp and more shrouded/cloudy? (don't have a better word for that). It has similar physical effects to TMA-2, although I find it more comfortable even though the bodyload is heavier. Don't exactly know why, maybe because its less stimulating and overall just very tranquil. It honestly even had more impressive CEV's than mescaline, which I didn't think was even possible, but DOM was gorgeous with my eyes closed. Mescaline was much more cheerful and easier going than DOM, which blindsided me by its sheer strength. Phenomenal and powerful drug, up there with LSD, Mescaline to be one of my all-time favorite psychedelics.
Will probably take some time to integrate this experience, but I'm very excited to return back into that space. I have a lot of respect for these psychedelic amphetamines and they are not for everyone but TMA-2, and especially DOM impressed me quite a lot so I'm excited how DOC, DOB and other DOX are gonna compare.
