Final answer:
The statement regarding college smokers starting before age 18 is true. Most smokers begin in their adolescent years, and quitting smoking proves to be challenging for many.
Step-by-step explanation:
The statement that out of college smokers, 8 in 10 started smoking before age 18 is True. Historical data and contemporary surveys consistently indicate that the majority of adult smokers initiate smoking during their teenage years. For instance, figures show a tendency for early initiation into smoking, with people often starting in their adolescent years, a pattern that continues despite the decline in overall smoking rates. Moreover, despite efforts to reduce tobacco use, such as the implementation of warning labels since 1965, smoking and its adverse health effects, such as lung cancer, remain a significant challenge. The addictive nature of nicotine, which is present in tobacco smoke, also contributes to the difficulty many experience when attempting to quit smoking, as demonstrated by the relatively low cessation success rates.
