When Florida police pulled a 19-year-old boy from the body of his victim who was biting him in the face on Tuesday, it was clear he was under the influence of a drug.
This was not the first case. Florida police killed a person in 2014 for attacking teenagers and trying to bite their face in what one witness described as "extraordinary."
The police linked these cases to the use of an industrial drug called Falcas, believed to increase and motivate animal zest for such acts.
What is flak?
Falacca is an industrial anesthetic known as alpha bipi, a cheap drug that is manufactured in China.
According to the American Institute for Drug Research, flakes take the form of white granules with a foul odor that can be eaten, inhaled, injected or used by electronic cigarettes.
Flax causes a state of delirium associated with paranoia and severe hallucinations, which can lead to violence.
The Institute has seriously damaged the drug as it could lead to a body temperature that could lead to death, as well as severe damage to the kidney.
The drug has spread in the past few years in the United States, specifically in Florida. The Food and Drug Administration has identified 38 cases of flax abuse in 2013 and 228 in 2014.
A state report in Florida said Broward County recorded nearly three cases of abuse each day.
An anesthetic leads to violence
The recent incident in Florida has reinforced the hypothesis that the drug is related to violence and attacks pedestrians on the streets, but is still under study.
There were videos on social networks showing people in a state of hallucinations and delirium, and connected to the flax.
