Drug info - Color of Molly (MDMA) changing over time, or due to crystallization?

[Richi]

Some molly was stored in aluminum foil for 4-5 days, and it changed from a light/off brown color to crystal white. Has anyone heard of this happening before?

One likely explanation is that the molly which was obtained in aluminum foil was larger white crystals to begin with. The rest came to swim as the light brown powder.

EDIT: I am adding some more pictures, on behalf of a foaf. Some of what is supposedly MDMA is completely crystal clear, and some of it is light brown. Is it likely that this is all MDMA, or could it be something else? Could some of the crystals of MDMA be more pure than others, all in the same batch?

The image of the container was taken right after a large clear crystal was broken up and poured out on top of the rest of it. This crystal was translucent to begin with. Other crystals are much darker, but when broken up, become much clearer.

It's worth it to note that this molly was more expensive, and described as better than the last batch, which was generally darker in color.

Was the "molly" tested with a Marquis kit? SWIM has never had any mdmda powder/crystals change colors on him, but he's only ever kept it in plastic baggies.

No it wasn't chemically tested, but has been field tested by many individuals, many times. It's mostly molly, but could potentially be cut with speed.

Yes all of it is MDMA. A foaf tried it and said it felt the same as mdma, not methamphetamine.
