Is MDMA damaged by heat?

I forgot a polythene bag with a few pills (anchors) on the top of a little oven in my kitchen for about ten minutes. The polythene bag was not melted so I think the pills were heated at 60 to 70 degrees Celsius.

Could this damage the MDMA?

If the pills were damp it probably would have caused some decomposition. If the pills were dry and they were only on there ten minutes the material will be okay.
