Having been unlucky enough to try some lab grade capsaicin, I can thouroughly assure you that was not anywhere close to what they should have experienced, passing a kidney stone, and crushing my l4 l5 vertebrea paled in comparison. I couldnt quite describe the sensation as pain, but more like having your tongue tattooed with needles that were electrified and coated in hydrochloric acid. Instant drooling and sweat that lasted till we were nearly dehydrated and the closest anything has ever brought me to hallucinations (though we may have been i think my brain still tries to repress the experience.)that wasnt intended for that porpose. The only visual aid that comes close is the scene in fear and loathing in las vegas where thompson supposedly tries the pure adrenaline.
No i will not ever do it again or put it on video unless you are offering a exorbitant amount of money, coupled with a nice term life insurance policy paid in full.
I forgot to mention the Extreme anxiety and feeling of impending doom and death that also accompanied the experience.
