When one considers the use of alcohol, nicotine, and caffeine, one finds that over ________ of the U.S. population use different types of drugs on a daily basis.

• A. 75%
• B. 88%
• C. 94%
• D. 98%

Answer: (B)

Daily use of widely available substances is incredibly common in the U.S. Caffeine stands out as the most pervasive daily stimulant, with most adults consuming some form of caffeine every day. When you consider that many people also use alcohol or nicotine on a daily basis, the portion of the population that uses at least one of these substances daily sits in the upper range of common experience. About 88% of Americans report using caffeine daily, and that figure helps explain why the overall share using any of these drugs daily is in the high eighties. The other options would imply a noticeably higher or lower level than what population data typically show for this trio of legal substances, so 88% best fits the observed pattern of daily, widespread use.
