In 2017, the study said, every German above the age of 14 drank 10.5 liters of pure alcohol, a slight decrease from 10.6 liters per person the year before.
Norwegians aged 15 and above, by comparison, consumed only six liters of alcohol per person.
"Germany is still one of the high-consumption countries internationally, despite declining consumption," the DHS study said.
According to the World Health Organization, Germany ranked fourth in the world in pure alcohol consumption per capita, behind only Moldova, Lithuania and the Czech Republic.
Dr. Tobias Effertz, a health economist, estimated in the DHS study that the economic cost of harmful alcohol consumption sits at €57.04 billion ($61.97 billion) per year. Government tax revenue from alcohol was €3.185 billion in 2018, the study points out.
However, the number of men and women smokers in Germany has been on the decline, the study said. As has smoking among young people, which the study says has been declining for 15 years. The study attributes the latter to tobacco control measures.
Effertz estimates the economic costs of cigarettes Germany to be €97.24 billion, €30.32 billion of which is direct costs, such as those for treating tobacco-related diseases, and €66.92 billion are indirect costs, such as the loss of productivity.
Legal and illegal drugs
Dependence on and abuse of medicine has continued to increase, the study said, particularly in terms of misuse of unnecessarily high doses of medications. The study estimates that between 1.5 million and 1.9 million Germans are addicted to prescription drugs, particularly sedatives, sleeping pills and non-opioid painkillers.
When it comes to illegal drugs, the study says 15.2 million adults between 18 and 64 and adolescents between the ages of 12 and 17 have admitted to trying an illegal drug once in their lives.
Cannabis remains the most popular illegal drug consumed, according to the study. It observed that, while cannabis consumption among young people declined in the 2000s, usage has increased since 2011. In 2018, 8% of adolescents between 12 and 17 consumed cannabis.
In 2018 there were 41,000 cocaine addicts in Germany, and 103,000 Germans were addicted to amphetamines. Almost 80,000 Germans were receiving some form of drug substitution therapy.
Police registered 1,398 drug-related deaths in 2019, a 9.6% increase over the year before.
