I do know the active ingredient is cytotoxic / potentially neurotoxic. Definitely avoid.

I was young and in a pretty ropey state of mind, living in a drab town in the Midlands in the sleety grey winter. A friend had tried it before which is where I got the idea. It tasted nasty and bitter, unsurprisingly for something you use by the pinch. Within an hour or two I became unpleasantly high, which made me regret what I'd done and worry myself into a classic bad trip state. It lasted for a long time, don't remember much of the evening, went to bed, couldn't sleep, missed an awards ceremony.

Next three days I was like a zombie - heart racing even sitting still, cotton-mouth, trouble stringing words together. Along with galloping shame and self-loathing.

To this day my friends give me shit me about it, whenever nutmeg is mentioned. I count myself lucky that it wasn't worse and that I still have friends from that time.
