Yeah but there all different, there's a big difference between LSD and mushroom or 2cb?
DOx is a group of chemicals.
The most common are DOC, DOB, DOM, & DOI.
Because of the small doses required they are sometimes found on blotter & sold as acid.
Most people have negative reactions to DOI & DOB - they also have very long durations, you'll be tripping over 20 hours.
That said some of them do have their fans - DOM especially is meant to be amazing.
