A whopping 28 percent of morning-after pills in Peru are fake. A study published today in PLOS ONE relates how some emergency contraceptives contain inadequate amounts of active ingredients that, in many cases, arent being released quickly enough into the body to be considered effective. In the study, researchers at the Georgia Institute of Technology tested 25 batches of emergency contraceptives purchased from 15 pharmacies and distributors in Lima, Peru. Peru isnt the only country that has had to deal with fake contraceptives.
