Androstene
A pharmaceutical created to treat some rare hormone imbalances; however, people taking the drug regularly now outnumber the estimated number of people suffering from those conditions by nearly 30:1. Androstene stimulates production of certain secondary sexual hormones in a precise pattern, creating powerful and predictable mental and emotional side effect. In men, specifically, the drug acts as a powerful aphrodisiac, also commonly creating homosexual urges in about 80% of the population. This generally (based on the doses of the 'purple pills' commonly supplied by street dealers) lasts between 2 and 3 hours.
Trying to reduce the recreational use of such a morally dangerous drug, the FCI Narcotics Taskforce has launched a media campaign with slogans such as "Say no to the Purple Pimp", personifying the drug as an untrustworth villain who robs and otherwise disadvantages his customers. A previous campaign, showing a young businessman known as Normanstanley emerging from the drug's effects in the embrace of six burly, hairy building labourers, was deemed 'too explicit' by a number of planetary broadcasting censors.
