But drug-poisoning deaths - mostly related to opioids -increased dramatically. However, researchers found that increases in drug overdose deaths resulted in a loss of an average of three months (0.28 years) in life expectancy.
Research suggests that the opioid crisis is having an impact on life expectancy in the US.
During this time, overall life expectancy increased by two years reaching 78-point-eight years.
The data was compiled by researchers from the Centers for Disease Control and Prevention and was published Tuesday in the Journal of the American Medical Association.
In fact, opioids are taking, an estimated, two and a half months off of our lives.
When the data is finalized, the CDC expects drug overdose deaths to top 64,000 for 2016.
The study's authors say that the number of opioid-involved poisoning deaths is likely underestimated, noting that up to a quarter of death certificates do not list the specific drug involved. "U.S. life expectancy decreased from 2014 to 2015 and is now lower than in most high-income countries, with this gap projected to increase".
