"My whole mouth went numb" This is a very strong indication for taking NBOME instead of LSD. From the article: "Looking back, I'm pretty certain that what I tried was not LSD." LSD would never numb your mouth. Just Google "LSD mouht numb reddit". Also, there's no lethal does of LSD, NBOM can easily kill you or screw you up just like in the article.

Everyone should always test thier substances before taking them to prevent these stories.

So do not fear LSD, fear NBOME.
