Self-study
Cigarette companies claim that manufacturing both low- and high-nicotine cigarettes allows smokers to choose how much nicotine they want. ████████ █ ██████ █████ ███ █████ ████ ███ ██████ ██ ████████ █████ ██ ███ █████ ██ ███████ ███ █████ ███ ████ ██ ██████████ ███ ███ ███ █████████ ██ ███ ███ ██ █ █████ █████ ██ ████████ ████████ ███ █████ ██ ████████ ██ ███ ██████████ ████ ██████
"Surprising" Phenomenon
Why do smokers who smoke one pack a day have identical levels of nicotine in their blod at the end of the day regardless of whether they smoke a pack of high-nicotine cigarettes or low-nicotine cigarettes?
Objective
The correct answer should give us a reason that the difference between high-nicotine packs and low-nicotine packs might not lead to a difference in nicotine levels in blood at the end of the day for smokers who smoke one pack.

Which one of the following, ██ █████ ████ █████ ██ ███████ ███ ███████ ██ ███ ████████ ██████
a
Blood cannot absorb ████ ████████ ███ ███ ████ ████ █████ ██ ███ █████ ████ █ ███████ ██ ███ ███████████████ ██████████ ██████████
This establishes a ceiling for nicotine in one’s blood and that low-nicotine packs already lead to nicotine levels at that ceiling. High-nicotine packs have more nicotine, but won’t go above the ceiling of nicotine levels in people’s blood.

Smokers of the ███████████████ ██████████ █████████ █████████ █████ ████ ██████████ ███ ███ ████ ███████ ██ █████████████ ███████████
The statistic in the stimulus involves smokers who smoke just one pack a day. This controls for varying amounts of cigarettes.

Most nicotine is ████████ ████ ███ █████ ██ █ ██████ ████ ██ ██ ██ █████████ ██ ███████ ███████████
Even if this is true, if low-nicotine packs have less nicotine overall, we would still expect less nicotine in their blood.

The level of ███ ██ ██████████ ██ ██████ ██ ████████████ ██████████ ████ ██ ██ ██ ████ █████████████ ███████████
We have no reason to suspect the level of tar in cigarettes impacts the level of nicotine in one’s blood.

When taking in ████████ ██ ███████ ██████████ ██ █████████████ ███ █████ ██ ████████ ██ ███ █████ █████████ █████████
We’re concerned about nicotine levels after smoking. What happens to nicotine when people stop smoking doesn’t help explain the identical nicotine levels observed after smoking.
