It wasn't a hallucinogenic designer drug, it was a botched attempt
at producing a meperidine analogue (i.e., a synthetic opioid), but
one of the unwanted by-products of the synthesis was MPTP, which
is metabolized to a paraquat-like substance which damages dopaminergic
neurons in the substantia nigra.
