Blue Shock looks like a shiny blue cough syrup and kicks like amyl nitrate’s bigger, stronger brother. Generally taken in doses of no more than a teaspoonful at a time, the immediate result of ingestion is agonising pain.
Fortunately, the pain wears off after a few seconds, leaving every nerve in the body more sensitive than usual. As such, it can be used to heighten sexual pleasure (and it is popular in Al Amarja’s S&M scene for both its effects).
Of course, having your sense of touch heightened also makes pain more intense, so it’s not all good. Not to mention the statistically improbable correlation between Blue Shock use and spontaneous combustion.
