SWIM finds 5-MeO-DMT taken sublingually to be more like acid than DMT is. The sublingual 5-MeO-DMT trip lasts about 1 hour only. It's VERY NICE. But don’t smoke it, it’s unpleasant when smoked.
Another DMT relative that SWIM likes is 5-HO-DMT (bufotenine). It's a little trickier to extract than DMT is, but worth it. The only problem is the minor side effects (nausea for about 1 minute, and some people get head tension from it). 100 grams of Vilca can get you about 3000 mg of 5-HO-DMT, that's 300 strong 10 mg doses. It's best vaporized like you would do with DMT. It's very unlike anything else. It's almost purely just a hallucinogen, and hardly at all psychedelic. 5-MeO-DMT is the opposite, like LSD, it's strongly psychedelic and only mildly hallucinogenic.
It’s like this from strongest to weakest:
Psychedelic: 5-MeO-DMT > DMT > 5-HO-DMT
Visual Effects: 5-HO-DMT > DMT > 5-MeO-DMT
Audio Effects: 5-HO-DMT > DMT > 5-MeO-DMT
Side Effects: 5-HO-DMT > 5-MeO-DMT > DMT
Duration: 5-HO-DMT (1 hr) > DMT (30 min) > 5-MeO-DMT (15 min)
Peak: 5-HO-DMT (10 min) > DMT (5 min) > 5-MeO-DMT (2 min)
Bad Trip Potential: 5-MeO-DMT > DMT > 5-HO-DMT
Euphoria: 5-MeO-DMT > 5-HO-DMT > DMT
Stimulation: 5-MeO-DMT > DMT > 5-HO-DMT
Total immersion: DMT > 5-MeO-DMT > 5-HO-DMT
Anyway, that's SWIM's view on it.
As you can see DMT is in the middle ground in most areas, except it wins in the side effect area in having the least amount of side effects, and is more immersive than 5-MeO-DMT or 5-HO-DMT. DMT is a complete entheogen with both psychedelic and hallucinogenic effects, while 5-MeO-DMT and 5-HO-DMT are incomplete entheogens, meaning that 5-MeO-DMT lacks strong hallucinogenic effects and 5-HO-DMT lacks strong psychedelic effects.
The reason some people will say that DMT is more hallucinogenic than 5-HO-DMT is because they didn’t try a full dose of smoked 5-HO-DMT. 5-HO-DMT can bring you to the “other side” with a smaller dose than what is needed for DMT, but few people venture deep into the 5-HO-DMT trip because of the side effects it can cause. About 30 mg of pure white crystal 5-HO-DMT smoked will bring you into the “other side”. SWIM has had far more intense and meaningful visionary experiences from 5-HO-DMT than he’s ever had with DMT. But the DMT experiences are always more immersive. With 5-HO-DMT, it’s like your watching a show or a movie, with DMT it’s like you’re inside it and part of it. It’s very different. Also DMT is usually more erratic, more unpredictable, because it’s much more psychedelic. Set and setting are key to having a good DMT trip, but mean nothing for 5-HO-DMT, because it lacks psychedelic effects. With DMT, if the trip goes south, you can have an extremely horrifying experience for a few minutes. But I’ve never heard of anyone having such an experience from 5-HO-DMT. I think it’s impossible, because it almost completely lacks psychedelic effects, and because of that you feel disconnected from the visions. It’s hard to explain, but people can have horrifying visions from 5-HO-DMT, and just sit there calmly thinking, “WOW that looks pretty scary. I wonder what I’m going to see next?”. It’s just like watching a movie.
If you’re in the mood for a great closed eye light show, 5-HO-DMT is the ticket. If you want LSD-style insight and other strong mental psychedelic effects, 5-MeO-DMT is the ticket (taken sublingually, not smoked). If you want a complete experience full of both psychedelic effects and visual effects DMT is the ticket.
