In todays early morning hours I had this awkward experience. Something happened that has occurred before, but only rarely.

I took 20 mg goo and after exhaling a sub break through journey started with an explosion of a yellow cloud filled with beautiful Chinese looking motives, dragons etc.

At the same time my lungs felt incredibly heavy, as if they were pressed together. It became difficult to breath. I had to concentrate fully on my breath taking to get enough oxygen. Don’t think I ever inhaled deeper. Due to this fact I can’t remember anything else of the trip. My focus was on the ‘wrong’ thing.

It seems that there is an amount of DMT that causes a sort of lung anesthetize. But only if you get the specific dose.

What are your experiences on this matter?

Are you sure it was the lung(s) itself? (Was it ACRB/MHRB goo or some other acacia goo)? Also, how did you vaporize it?

Could it be laryngospam? We heard, pursed-lip-breathing could help when the heaviness/difficulty starts. There is also an acupressure point behind the earlobe.

Laryngospams can be caused by inhaling fumes/vapors that the boday isn't used to.....(we think) It can also be caused by swallowing undiluted essential oils, such as mint oil.....
It ain't a disease, it's moar of a reflex....(we think)

That being said....we also experienced breathing problem (1 1/2 hrs into the trip) with strong dose oral DMT/haoma.....so there could be other causes as well.....anyway, that was moar loike forgetting (the necessity) to breathe....

Thanks for your response.

It was DMT extracted from MHRB. Re X only once. So the extract contains (mostly) DMT and some other alkaloids. That’s why I call it goo. I vaporized it with a GVG.

I am not sure it were my lungs. I have read your references and will keep the pursed-lip-breathing in mind.

You have been helpful.

Are you a vegetarian? We try to eat natural calcium and natural magnesium (green stuff). Broccoli, basil (pesto...etc) and grana padano (cheese) has loads of natural calcium.

These three together with pasta are also very delicious. There is also (some) mineral waters that are rich in natural calcium. Laryngospasm can be a side effect of low calcium blood levels. Not meant as a medical advise - just eat healthy.....

Have you ever wondered why a rotting/dying broccoli stinks loike baby poo? It's because it is full of calcium.....

FTR, it's sulphur. Otherwise chalk would be the stinkiest substance known, which it clearly isn't.

Apologies for lack of other relevant input here

Sulphur itself is quite odorless.

Isothiocyanates (a class of compounds containing sulphur) on the other hand...

An isothiocyanate called sulforaphane is part of the smelly stuff in broccoli.

Other vegetables and herbs also contain these meanies, eg. horseradish.

I have been out-pedanted. Indeed, sulphur compounds.

Curiously enough, I was thinking about sulforaphane this past evening, even before I read this thread.

Commercial sulphur I have found to have a slight odour, presumably due to very slight oxidation or hydrolysis of impurities.

I think sulphur reducing bacteria would be a more likely culprit, since they convert elemental sulphur to H2S (hydrogen sulfide), which is known for its rotten egg smell.

But my sulph/fur smells more like SO2
