(CNN) – Fentanyl is the drug most commonly used in overdose deaths, according to a new report by the US government.
Data from the National Center for Health Statistics shows that the incidence of drug overdose associated with synthetic opioid increases by about 113% each year between 2013 and 2016.
The number of all overdoses increased by 54% each year between 2011 and 2016. In 2016 there were 63,632 deaths from overdose drugs.
Fentanyl was implicated in almost 29% of overdose deaths in 2016. Fentanyl was involved in only 4% of all drug addiction deaths in 2011. At that time, oxycodone is the most commonly used drug, accounting for 13% of all cases of fatal overdose.
From 2012 to 2015, heroin becomes a drug most commonly associated with overdose mortality. In 2011, the number of fatal overdoses for heroin was 4,571, or 11% of all deaths from drug use. In 2016, this figure has more than tripled to 15,961 deaths, representing a quarter of all cases of drug overdose this year.
The authors of the new study also found that most overdoses include more than one drug. In 2016, 2 out of 5 deaths from overdoses related to cocaine included fentanyl. Almost one third of overdoses associated with fentanyl also include heroin. More than 20% of fatal overdoses associated with methamphetamine are also associated with heroin.
In 2016, more than 18,000 deaths due to overdose include fentanyl and 16,000 deaths due to heroin.
Although many experts have pointed out the surge of prescription painkillers as the main cause of the opioid crisis in the United States, they say it first evolved to a heroin crisis and now to a fentanyl outbreak.
Over the review period (2011-2016), the number of drug overdoses containing methadone was reduced.

But Dr. Andrew Collodny, a co-founder of doctors for responsible prescribing of opioids, warned of the possibility that these interpretations could be interpreted as an end to the problem of prescription drugs. Colloid, who did not participate in the study, pointed out countries like Oklahoma where deaths from overdose with prescription opioids still exceed the deaths of heroin and fentanyl.
"Fentanyl is very deadly, in the geographical areas where it flooded, deaths have increased, as never before," he said.
Much of the focus of the drug crisis is on opiates, but also the number and deaths associated with cocaine and methamphetamine.
In the same six-year period, cocaine is the second or third most commonly used drug, and methamphetamine overdose has tripled.
Cocaine deaths almost doubled between 2014 and 2016, from 5,892 to 11,316 deaths from overdoses.
The authors of the study use textual analysis to assess the deaths of specific drugs. They found that the first 10 drugs in the six-year period are still the same and belong to three classes of drugs:
– Opioids such as fentanyl, heroin, hydrocodone, methadone, morphine and oxycodone
– Benzodiazepines like alprazolam and diazepam
– Stimulants like cocaine and methamphetamines
The study found that illegal drugs such as fentanyl and heroin were the main causes of unintended overdose and that prescription drugs are more likely to be involved in suicide overdoses.
