erototoxin
 n.— «Pornography triggers myriad kinds of internal, natural drugs that mimic the “high” from a street drug. Addiction to pornography is addiction to what I dub erototoxins—mind-altering drugs produced by the viewer’s own brain.» —“The Science Behind Pornography Addiction” by Judith Reisman U.S. Senate Committee on Commerce, Science, & Transportation Nov. 18, 2004.
