I wonder about this every time I replace a coil that is toasted. There are several types of coils now (Ni, kanthal, stainless) - it'd be nice to know more about the degradation of the metals and its effects for sure.
Nothing will happen until psychedelics are rescheduled. It's a travesty that even the "natural" tryptamines (psilocybin/psilocin and DMT) can't be researched more easily.
