More than 7 million people die every year due to tobacco use, costing households and governments more than $1.4 trillion in healthcare costs and productivity loss, experts wrote in a news release.

In addition, tobacco waste contains more than 7,000 toxic chemicals that poison the environment and contributes to 16 percent of all noncommunicable disease deaths.

The drug is a threat to livelihoods, too, according to the WHO. Around 860 million adult smokers live in either low- or middle-income countries, often spending more than 10 percent of their income on tobacco products and leaving less for things such as food, healthcare and education.

According to the Atlanta-based Centers for Disease Control and Prevention (CDC), smoking is the leading cause of preventable death in the U.S. with more than 480,000 annually reported deaths (nearly one in five deaths) and 16 million Americans suffering with at least one disease caused by smoking.

This costs the country nearly $170 billion in direct medical costs.

Nationwide, according to 2015 data, 31.4 percent of U.S. high school youth reported using a tobacco product and 10.8 percent reported smoking cigarettes.

In Georgia, approximately 11,700 adults die from smoking-related illnesses every year, according to CDC data.

A previous study by personal finance website WalletHub found Georgia's lifetime cost per smoker to be $1,155,351.

While the state doesn’t have a comprehensive smoke-free law to protect folks from secondhand smoke everywhere, five Georgia cities, one county, 33 University of Georgia campuses, 163 hospitals and 116 public school districts have adopted either tobacco-free or smoke-free policies.
