The World Health Organization (WHO) has confirmed that the painkiller fentanyl has been detected in several countries, with some in Southeast Asia and the Pacific region.
The WHO has also confirmed the presence of the pain reliever benzodiazepine hydrochloride (C-4765), the second most common opioid analgesic, in the Philippines.
In a statement, WHO officials said they were investigating a possible new case of fentanyl overdose in the country of Brunei.
The report comes amid a national conversation about the dangers of opioids and their possible links to deadly overdoses.
“It is not possible to determine whether the deaths are linked to the use of these opioids,” WHO officials wrote in the report.
“We do not yet have evidence of the use or misuse of these medications in the populations of countries, where they are available.”

It is not addictive, has no side effects and is approved for the treatment of pain in the US, UK, Canada and Australia.
Fentanyl and benzodiazapine are often sold by online retailers, but it is illegal to buy the drugs online.
“The most important thing to note is that fentanyl has no effect on the brain or body, and the side effects are extremely mild,” the WHO statement said.

“The report noted that the number of cases of fentanyl-related deaths in the United States is now up to 16.
