Investigations into the cause of the Incident began immediately but were hindered by the chaos - they properly resumed 5 days after the "epidemic", when law and order were completely re-maintained, and when the WTEA had pacified paranoid individuals.
Scattered incidents of libido spikes occurred here and there before they stopped entirely by the end of the week.
Partnering with worldwide and countrywide political organizations, the WTEA carried out its mass investigation, attempting first to find the cause of the mysterious Incidents.
Chasing the possibility that the libido spikes were the results of a contamination, the WTEA left no stone unturned.
They were looking for something that could at least identify as an aphrodisiac.
They started with water, then turned to drinks. Food. Beauty supplies - perfume, makeup, hairspray, etc. Soap. Shampoo. Household cleaning supplies.
They discovered an unusual plant-based chemical compound in a select type of Colgate-brand "Max Fresh" toothpaste.
It was the brand that all victims of the libido spike used that morning.
And all the tubes were new.
The compounds had begun to "denature" at the front of the tubes, but were still intact at the back of it.
Though similar in structure to the aphrodisiac compounds found naturally in the Ginkgo Biloba or "Maidenhair" Tree, when tested, the compound proved over 7 times more effective at increasing libido than the natural compounds.
What was also found in the toothpaste was an abundance of bizarre DNA that appeared to be a mix between that of a human and of a plant - the Gingko Biloba.
And it was then that the cause of this mess was likely a plant mutant's special secretions (a quite common occurrence among plant and plant-like mutants), that was either unintentionally or maliciously somehow mixed into the toothpaste.
And so, after recalling and containing the toothpaste, the WTEA went to the factories.
