Swim had very similar questions once, many MHRB extract batches ago. Can you confirm the extract's shape and colour..? did crystals form..? Yellow extract is different in its effects, and better 'burning' - it makes HUGE clouds of vapour as it 'ignites' easier, for milliseconds. Have you had a chance to compare white to yellow dmt, mr 'Dabear...? Learning how to smoke - the residues should tell something about the quality of spice too. Quality extract re-grows nicely, in 'shards' of small crystals all over the glassware, no...? And putting all questions about bad-spice-from-bad-teks aside, let me just ask; But what is a breakthrough..? some how it seems so hard to predict or 'call' or define. Everyone is so different, and will call it something else - what is wordified into language and the 'cartoons' in our heads is NOT it either ! That's just the languaged-thing we do so well with reality. Words barley point at an ineffable experience, or throw mud on it, to 'reveal' it's form. They barely laminate bits of it ... we can remember... Swim thought she had spice with 5-Me-O-dmt in it - the AllThatIs just appeared so easily ... That white out Bliss seemed to be the trip - it IS the trip so often ! ... Other times bad, oxidized spice, and lye-contaminated spice led to poor trips. To get her confidence up, or confirm that she had not 'ruined' her brain's HT5-receptor count permanently, she made pristine, pure new batches of nn-dmt via Acid-Base separation. This proved that God is even closer than before ... and dmt still scares her, but all is ok. "Breakthrough" or no breakthrough ... it is just a drug, or a 'sacrament' ... risky, and rewarding in it's unique way to each of us. Try eating some with MAOI..?! So I would say don't expect from wordified-models, that your experience or your 'entites' could be like anyone else's. Even though after some tries, you'll understand why some people's words-and mental-cartoons try to get at it, and other words just fail. Swim's were much different than she expected too. The question posed makes me think of lots of similar experiences swim had told me about. I theorized from those stories of hers that we may all be different, molecular-genetically-down to the genes, so that some of us have experiences that lack a 'breakthrough' type event. For example - only 20% of Rick Strassman's patients encountered 'entities' - why is this ? ... that means that 80% of the time you'll likely NOT 'meet' any creatures, angels or anything but yourself. I wonder if this is a genetic trait - to be so predisposed, as to have uber-sensitive HT5-recepors all in your brain (... or whatever makes you genetically able to see entities.) Also don't forget that 2% of the population see's entities without needing dmt... I also theorized about diurnal rhythms in our brain's receptor-numbers, based on swim's extensive tales of trials-and-error with pipe-types, spice quality (lye-contaninated.>!) and settings. Swim made me think that there is a possibility that our brains have breakthroughs because of the number of serotonin ('HT5") receptors present and MAO-activity. If you have a slightly lower number of serotonin receptors made and ready, the moment you inhale 35 mg, it may be that you get a certain type of trip. The MAO activity and HT5-receptor numbers change every hour of the day, as we eat, get tired, sleep, etc... How does this affect the effectivness of 35 mg, perfectly vapourized..? Someone said they eat bacon and beans, lots of them, just before trying dmt. This is to deliberately flood their body's MAO enzymes with tyrosine (in the bacon and beans), so the trip is different ! Imagine the smell ! Smokin' bacon and dmt ! So if you're genetically predisposed ( of the 2% that are broke-open already) maybe it's quite normal to 'slip' through ... into the White Light ?
