It’s smoking tobacco and drinking alcohol — and not taking illegal drugs — that pose the greatest risks to people’s health, a new international study contends.
Researchers found that alcohol and tobacco use combined cost more than a quarter of a billion disability-adjusted life-years worldwide, while illegal drugs only accounted for tens of millions in comparison. Disability-adjusted life-years is a measurement of overall disease burden, expressed as the number of years lost due to ill health, disability or early death.
Worldwide, more than one in seven adults smoke tobacco, and one in five reports at least one occasion of heavy drinking in the past month, the review of 2015 data found.
Central, Eastern and Western Europe have the highest alcohol consumption per person, and the highest rates of heavy consumption among drinkers (50.5 percent, 48 percent, and just over 42 percent, respectively), according to the report.
Those same areas also have the highest rates of tobacco smoking — Eastern Europe 24.2 percent, Central Europe 23.7 percent, and Western Europe almost 21 percent.
Illicit drug use was far less common worldwide, with fewer than one in 20 people estimated to use marijuana in the past year, with much lower rates of use for amphetamines, opioids and cocaine, the researchers said.
But the United States and Canada had among the highest rates of dependence on marijuana (749 cases per 100,000 people), opioids (650 cases per 100,000) and cocaine (301 cases per 100,000), according to study co-author Robert West, of University College London, and colleagues.
In addition, Australia and New Zealand had the highest rate of amphetamine dependence (491.5 per 100,000 people), as well as high rates of dependence on marijuana (694 cases per 100,000 people), opioids (510 per 100,000) and cocaine use (160.5 per 100,000 people).
The study was published online May 11 in the journal Addiction.
In a related development, it was reported that many mental health and addiction treatment centers in the United States don’t help patients quit smoking, according to a new government study.
People with mental illness and/or drug or alcohol addiction are far more likely than others to smoke cigarettes. And they are more likely to die from a smoking-related illness than from a behavioral health condition, according to the report from the U.S. Centers for Disease Control and Prevention and the U.S. Substance Abuse and Mental Health Services Administration (SAMHSA).
But stop-smoking assistance is limited at behavioral health centers, said Corinne Graffunder, director of CDC’s Office on Smoking and Health.
“Many people with mental health and substance abuse disorders want to stop smoking and are able to quit, and can do it with help,” Graffunder said in a CDC news release.
“Too many smokers lack access to proven interventions that could ultimately help them quit smoking,” she added.
Analyzing 2016 data, the researchers found that only 49 percent of mental health treatment facilities were smoke-free. And about one-third of addiction treatment centers were smoke-free.
