Identify two protective factors against health risks from smoking, and nine risk factors for it. Also cite a statistic on tobacco-related deaths in the USA.​

A. Having smoked fewer than 100 cigarettes in one's lifetime is protective factor.
B. Having smoked between 100-200 cigarettes in one's lifetime, but not having smoked any in over five years, and not wanting to smoke, also protect against health risks.
C. Smoking more than 10 cigarettes daily is a health risk.
D. Smoking more than two packs of cigarettes a day (>40 cigarettes) is even worse.
E. Believing that smoking's health risks have been exaggerated is itself a health risk.
F. Believing that smoking is likely harmful, but one will stop before realizing those harmful effects, is a health risk.
1. Damage can occur before it is identified.
2. Also, it is notoriously difficult for many people to quit smoking.
G. Some people think it is safer to smoke cigars or pipes than cigarettes, but tobacco smoking is still a health risk regardless.
1. People who think health problems are a low risk with smoking cigars or pipes are mistaken.
H. Some people think e-cigarettes are safer than paper cigarettes-especially young adults, who are using them more than regular cigarettes now.
1. Although e-cigarettes are not proven harmful, evidence is accumulating that they are.
I. Non-smokers who live with smokers are at risk for health problems from passive inhalation (secondhand smoke).
J. People who use chewing tobacco, snuff, or other smokeless tobacco daily are also at risk for health problems.
K. Tobacco products are accountable for approximately 480,000 deaths annually in the USA.
The majority of these fatalities are from cancer, cardiovascular disease, and chronic lower respiratory disease (i.e. chronic obstructive pulmonary disease/COPD).
