Ok. So here's a few things that have been on SWIM’S mind for a while. SWIM once remembers reading somewhere that tryptamines such as dmt, while psychoactive in humans, acted as a natural repellant to insects for plants.
SWIM has on many occasions had nice white freeze pecipitated crystals, but finds that the more the spice is recrystalised, the stronger the taste gets. While the smell remains fairly normal for spice, leaving behind that strange but ridiculously familiar smell, the taste is sometimes a very 'mothbally' kind of taste.
What SWIM wonders is, if you look at Napthalene Flakes, which are basically mothballs, and repell insects, is it possible that the “mothball” taste of the defatted/recrystalised , supposedly pure spice is representative of this “napthalene / insect repelling “ like quality of the plant? Or is it more likely that this quality is due to Naptha (Shellite) possibly becoming trapped during a final re-x evap, and the taste coming through into the spice?
If swim was to sacrafice a few crystals in a spoon, and heat them from below, he finds that the crystals disolve into an clear oil, and if he places direct flame onto the oily puddle, it does not catch fire which one would think would indicate that there’s no solvent trapped in the spice??? For the puddle to catch fire, SWIM would have to heat puddle right up and place a flame directly onto the puddle for 20 seconds or so before it would ignite the oil. After burning out, it leaves a brownish residue. SWIM wonders if anyone else has ever tried, or is willing to try this themselves and report their findings. SWIM is interested if this is normal?
SWIM has travelled deep on many occassions, and sampled a variety of differently sourced spices, as well as his personal , so is not a total newbie, but is still lost for an explanation to this. Any replies would be appreciated.
Another thing SWIM came across the other day thats got him fucked, is that he had some spice which had been in a sealed glass pyrex bowl and chucked in the freezer. The spice had been sitting there for a few weeks and was on this occasion, scraped up (about ¾ gram), and placed into a little baggie. Now these crystals had been re-x’d twice and on the 3rd re-x, as they were placed outside for a while to “finish drying”, SWIM came back out to find that his once beautifully formed white crystals had half melted back into a puddle and turned slightly orangish. This was then immediately taken back inside, about 30ml of Shellite heated to about 40 degrees celcius, and the spice redisolved back into it then again, left in a COOL PLACE to evap this time. (what was SWIM thinking?) Anyway, the spice recrystalised ok, just still had a slight orange tinge to it...So SWIM has scraped these new crystals outta the pyrex bowl, into a baggie (3/4 gram) and headed over to a mates, but upon arriving has found that the chunky crystals have turned from an offwhitish pile of heavy shards into a puddle of clear to orangish GOO??? Now SWIM has never really bothered to keep spice in a freezer before, other than when performing a freeze precipitation, so wonders what the fuck has happened here? The spice was only in his pocket, straight out of the freezer for like 20 minutes and had somehow turned into what resembled a gooey like oil??? Again, is this normal? SWIM has left spice in baggies for up to three months before as he only journey’s on rare occasions for the purpose of personal healing, but he has never had a problem like this before. Some of this goo was burt on a spoon as reported above, and the remainder chucked back in a freezer to see what would happen to it. SWIM will post a pic. Any thoughts apprecitated. 

So SWIM chucked his baggie back in the freezer as it was, just out of interest, and after about 12 hrs he'd noticed that the spice has turned back in to an offwhitish paste inside the baggie? SWIM takes the bag out to photograph and within minutes it is reduced back to an clear to orangish goo??? The two pictures below show spice coming out of freezer beging to paste up, while the second pic shows the spice within 5 minutes, as it turned back to an oil???

Most likely solvent traces inside of the crystals warming up and making it melt. I suggest not storing dmt in a baggy but rather a glass vial kind of thing. Also, you can recrystallize this that you have, then check the FAQ for retrieving crystals from freeze precip without the melting problem, and then redissolve your crystals with pure acetone/ethanol and re-evap to remove the solvent traces.

Thanks endless...the spice had been stored in pyrex glass for a few weeks and only placed in bag 10 minutes before going out to a mates. have never had this problem before...maybe a dud batch of solvent, although SWIM uses the same shellite as always and previously perfomed evap tests on it? thanks agagin endless

Evap test and previous success are good sign, yeah. Also I guess you checked the MSDS of the solvent?

What about possible impurities or things in the plastic itself? Maybe some weird plasticizers or what not that in contact with small traces of solvent/high-ph dmt have reacted in some way?

In any case my suggestion still stands of recrystallizing (or doing a small a/b on it and pulling again), then the ethanol/acetone thing, and next time not using these baggies. Good luck!
