I recently procured a gram of Tetrahydroharmine hcl after reading of it's synergy/potentiation of DMT. I tried ~25mg sublingually the other day just to get a feel for it and noticed a subtle but nice feeling of well being and warmth. Still, the effects weren't very strong. About 1.5 hours after absorption. I decided to try a small amount of DMT. I loaded 10mg into my vaporgenie and vaporized it in 2 hits.

The experience was very nice and surprisingly intense though quite gentle as well. The effects of the THH are very apparent when combined with DMT. One of my favorite things is that once you come out of the peak, the very pleasant after effects last for another 30min or so in which your thought patterns are altered quite significantly. Much more similar to a conventional trip (like mushrooms or LSD) in which you can ponder the what you just experienced. An absolutely beautiful mind state.

This was about 5 days ago. I have a few questions for others who have used or have knowledge of THH.

How long do the effects last for each ROA?
How long does tolerance last? Can I have a session with it in the morning and another one at night?
What sorts of dosages have people been using? Although higher doses are unnecessary it would be interesting to see how it affects the experience.

I will use this thread to further document my experiences with THH and DMT.

Dang this place has been quiet this week. I just wanna have a little discussion with someone who has experience with THH. Anyone around?

Sorry I don't know about THH, but I wanted to ask you a quick question about your Vaporgenie technique. Do you use a herbal bed with the VG? What is the maximum possible amount of spice to load into the VG?

Depending on how much harmine and harmaline is added, it can be significantly comparable to that of an authentic ayahuasca session. However, the pure substance is very sedating to say the least but after that first hit of DMT the effects become very apparent, lasting varying hours from 2-5 hours. Usually SWIM tries to spread out his pharmahuasca nights through a monthly dose of aya and tolerance buildup has been mutual over time. The nausea buildup seems to subside after the initial onset, passing 10-20mins.

SWIM weighs about 175lbs and found a threshold dose with these three at 150:50:50mg. However, THH potentiates the spice even at smaller doses sublingually. He has tried this under a capsule at 50mg, give or take, and onset was very similar passing at around an hour or so. But for SWIM, he needs the conjunction of the three for it to function.. the way he wants it at least.


Just don't let it overflow to that you can't put the bowl back on
It's usually around 80-150mg, really depends.. but as the herb bed is recommended, its not really necessary.

You kinda need a herb bed unless you get a few extra screens. That's what I did. If you go on their website, they will send you extra screens and pipe cleaners for you VG. Put like 4-5 screens in the bowl and then you don't need any herbal bed. Not only do you get pure hits but this way also seems to make it much smoother.

I am mostly interested at this time in it's affect on smoked DMT. I have yet to try any form of huasca. I do plan on doing so eventually but I just love the short duration of smoked DMT. So different from my other experiences with LSD/mush etc in that regard.

I'm about to dose 50mg sublingually and once I feel effects I will smoke a decent amount of MJ. I heard it has a great synergy with cannabis. Towards the tail end of the THH I will smoke some spice as well. I will report back soon.

I've tried Caapi tea + oral freebase DMT twice now.. and my recommendation is to avoid oral freebase, as it's very hard on the stomach. Convert some to the fumarate salt form if you can. Caapi + smoked DMT is amazing though. Have a good journey.

Salt forms of DMT are digested much more rapidly and are easier on the stomach. Maybe the traces of naphtha normally present in the freebase DMT are bad on the stomach and making it into a salt helps to remove these traces? I’m not use. At any rate, use a salt form for oral use, pretty much everyone says its better.

ChemEng- how much caapi leaf do you use when you make a tea to use in conjunction with smoke spice? do you use fresh or dried leaf? some strange guy down the street who i've never met before in my entire life is thinking about buying some caapi leaf for smoking with spice and (now) making tea to go along with smoking spice.....

love and gratitude!

I used shredded/powdered caapi root with a THP extraction to make the tea. It was extracted from about 15 g of powdered caapi per dose. The other way to get MAOI is with syrian rue which I haven't tried. I hear is much easier to work with but gives a different experience.
