SWIM has on occasion used DXM out of curiosity. It's not enjoyable really. It detaches you from everything and makes it seem like nothing is important. You get into a foggy head state, there are visual effects, and the like, but the entire trip feels like your just out of it, not able to focus, just sort of drifting, as if about to fall asleep. It has no real qualities I would say are positive.
DXM is for people that want a mental vacation, an escape from the mind, not a journey into the mind. In that respect it's not psychedelic at all. It's the opposite of a psychedelic. The only thing it shares with true psychedelics is that there are visual effects.
SWIM has a whole bottle of these things in pure form and doesn't know what to do with it. They are not very effective as cough medicine. SWIM has no idea what to do with them.
Does DXM go well with anything that is actually psychedelic?
