I don't know about feeling like you're going to die but smoked 5-MeO-DMT can be very scary if the dose is high enough, even for those who are very familiar with psychedelics.

5-MeO-DMT is usually not visual for most people, and has LSD-style mind fuck, but more so than LSD. However, for some people 5-MeO-DMT is more visual than DMT.

Also, for SWIM, 5-HO-DMT (bufotenine) is more of a visionary trip than DMT ever is (unless DMT is taken with harmalas). But some people find the opposite to be true.

Not everyone is affected the same way.

With smoked 5-MeO-DMT, it’s roughly 5-10 times more potent than DMT. It comes on REALLY FAST. Before you exhale, you’re already tripping. It peaks after about 2 minutes and the whole trip lasts only about 15 minutes. So while it can be vary scary, the trip is really short and by the time you notice its scary, it’s already starting to end.

SWIM doesn’t like smoked 5-MeO-DMT much. However, taken sublingually it can be a very beautiful experience. SWIM prefers to use Virola theiodora resin because no extraction is needed. You mix 6% (by weight) calcium hydroxide with it and take about 500-1000 mg of resin for a starting dose. You mix a little water and make a pill shape out of it and put it in your cheek and suck on it. When done that way, the effects start after about 5 minutes and peak after about 10-15 minutes and the whole trip lasts about 45-60 minutes. It’s MUCH NICER.
