Nearly 100% of adults who smoke every day started smoking when they were 26 or younger, so prevention is the key.
Preventing Tobacco Use among Youth and Young Adults: A Report of the Surgeon General
US Department of Health and Human Services
National Academies of Sciences, Engineering, and Medicine. "Public Health Consequences of E-Cigarettes." Washington, DC: The National Academies Press, 2018.
Millions of Americans use e-cigarettes. Despite their popularity, little is known about their health effects. Some suggest that e-cigarettes likely confer lower risk compared to combustible tobacco cigarettes, because they do not expose users to toxicants produced through combustion. Proponents of e-cigarette use also tout the potential benefits of e-cigarettes as devices that could help combustible tobacco cigarette smokers to quit and thereby reduce tobacco-related health risks. Others are concerned about the exposure to potentially toxic substances contained in e-cigarette emissions, especially in individuals who have never used tobacco products such as youth and young adults. Given their relatively recent introduction, there has been little time for a scientific body of evidence to develop on the health effects of e-cigarettes.
Public Health Consequences of E-Cigarettes reviews and critically assesses the state of the emerging evidence about e-cigarettes and health. This report makes recommendations for the improvement of this research and highlights gaps that are a priority for future research.

The U.S. Surgeon General has concluded that the burden of death and disease from tobacco use in the United States is overwhelmingly caused by cigarettes and other combusted tobacco products. Proven population-based interventions, including tobacco price increases, comprehensive smoke-free laws, anti-tobacco mass media campaigns, and barrier-free access to tobacco cessation counseling and medications, are critical to reduce cigarette smoking and smoking-related disease and death among U.S. adults, particularly among subpopulations with the highest prevalences.

Each year, the American Cancer Society estimates the numbers of new cancer cases and deaths that will occur in the United States and compiles the most recent data on cancer incidence, mortality, and survival.
Cancer is a major public health problem worldwide and is the second leading cause of death in the United States. In this article, we provide the estimated numbers of new cancer cases and deaths in 2018 in the United States nationally and for each state, as well as a comprehensive overview of cancer occurrence based on the most current population‐based data for cancer incidence through 2014 and for mortality through 2015. We also estimate the total number of deaths averted as a result of the continual decline in cancer death rates since the early 1990s and quantify the black‐white disparity in cancer mortality by state and age based on the actual number of reported cancer deaths in 2015.

CA: A Cancer Journal for Clinicians, November 21, 2017.
Contemporary information on the fraction of cancers that potentially could be prevented is useful for priority setting in cancer prevention and control. Herein, the authors estimate the proportion and number of invasive cancer cases and deaths, overall (excluding nonmelanoma skin cancers) and for 26 cancer types, in adults aged 30 years and older in the United States in 2014, that were attributable to major, potentially modifiable exposures (cigarette smoking; secondhand smoke; excess body weight; alcohol intake; consumption of red and processed meat; low consumption of fruits/vegetables, dietary fiber, and dietary calcium; physical inactivity; ultraviolet radiation; and 6 cancer-associated infections).

In 2015, approximately one in five U.S. adults (48.7 million) currently used any tobacco product, with most using combustible tobacco products. Any tobacco product use was significantly higher among males; adults aged <65 years; non-Hispanic AI/AN, whites, blacks, and persons of multiple races; persons living in the Midwest; persons with a GED; persons with annual household income <$35,000; persons who were single/never married/not living with a partner or divorced/separated/widowed; persons who were uninsured or insured through Medicaid; persons with a disability; and persons who identified as LGB. Adults with serious psychological distress had the highest prevalence of any tobacco product use of any subpopulation.

Cigarette smoking has declined considerably among U.S. adults over several decades; however, increases have occurred in the use of noncigarette tobacco products in recent years, and the use of multiple tobacco products has become common among current users of noncigarette tobacco products.

The workplace is a major source of exposure to secondhand smoke from combustible tobacco products. Smokefree workplace policies protect nonsmoking workers from secondhand smoke and help workers who smoke quit. This study examined changes in self-reported smokefree workplace policy coverage among U.S. workers from 2003 to 2010–2011.

Even though the effects of overweight and obesity on diabetes, cardiovascular disease, all-cause mortality, and other health outcomes are widely known, there is less awareness that overweight, obesity, and weight gain are associated with an increased risk of certain cancers. A recent review of more than 1000 studies concluded that sufficient evidence existed to link weight gain, overweight, and obesity with 13 cancers, including adenocarcinoma of the esophagus; cancers of the gastric cardia, colon and rectum, liver, gallbladder, pancreas, corpus uteri, ovary, kidney, and thyroid; postmenopausal female breast cancer; meningioma; and multiple myeloma.

Over the last decade, the use of electronic nicotine delivery systems (ENDS), including the electronic cigarette or e-cigarette, has grown rapidly. More youth now use ENDS than any tobacco product. This extensive research review shows that there are scientifically sound, sometimes competing arguments about ENDS that are not immediately and/or completely resolvable. However, the preponderance of the scientific evidence to date suggests that current-generation ENDS products are demonstrably less harmful than combustible tobacco products such as conventional cigarettes in several key ways, including by generating far lower levels of carcinogens and other toxic compounds than combustible products or those that contain tobacco. To place ENDS in context, the authors begin by reviewing the trends in use of major nicotine-containing products. Because nicotine is the common core—and highly addictive—constituent across all tobacco products, its toxicology is examined. With its long history as the only nicotine product widely accepted as being relatively safe, nicotine-replacement therapy (NRT) is also examined. A section is also included that examines snus, the most debated potential harm-reduction product before ENDS. Between discussions of NRT and snus, ENDS are extensively examined: what they are, knowledge about their level of “harm,” their relationship to smoking cessation, the so-called gateway effect, and dual use/poly-use.
"AACR Cancer Progress Report." Philadelphia: American Association for Cancer Research, September 13, 2017.
With the number of cancer cases diagnosed in the United States rising every year, it is vital that the AACR increases public awareness about cancer and the importance of research for improving health and saving lives from cancer. The annual AACR Cancer Progress Report is a cornerstone of these educational efforts and the AACR’s work to advocate for increased funding for the federal agencies that are vital for fueling progress against cancer— in particular, the National Institutes of Health (NIH), the National Cancer Institute (NCI), and the Food and Drug Administration (FDA).
The Report is released in September of each year and highlights advances over the past 12 months in the prevention, detection, diagnosis, and treatment of cancer. It also includes the personal experiences of cancer survivors who have benefited from these advances. Together with the developments described in the report, these survivor stories provide hope for a much brighter future for cancer patients and their loved ones.

Despite extraordinary progress in tobacco control and prevention, tobacco use remains the leading cause of preventable disease and death in the United States. Combustible cigarettes cause the overwhelming majority of tobacco-related disease and are responsible for more than 480,000 U.S. deaths each year. Indeed, when used as intended, combustible cigarettes kill half of all long-term users.

"Impact of HPV vaccination on oral HPV infections among young adults in the U.S.." Meeting Library, ASCO University, June 5, 2017.
The incidence of HPV-positive oropharyngeal cancers has risen in recent decades among US men. The potential impact of HPV vaccines on oral HPV infections has yet to be evaluated in efficacy-trials or surveillance studies.
HPV vaccination substantially reduced vaccine-type oral HPV infection prevalence among young adults (ages 18-33 years) in the US population during 2011-2014. However, due to low vaccine uptake, population-level effectiveness was modest overall and particularly low in men.

Quitting cigarette smoking greatly reduces the risk of developing smoking-related diseases; although the health benefits are greater for people who stop at earlier ages, there are benefits at any age (1). The use of electronic cigarettes (e-cigarettes) has increased in the United States (2). Little is known about how the rise in e-cigarette use, particularly among current and former adult cigarette smokers, may have affected quitting behaviors. This study assessed common methods used to try to quit cigarettes among a nationally representative online sample of US adult current smokers surveyed from April 2014 through June 2016.
