Does a greater tolerance for alcohol lower a person's BAC?

True
False

The correct answer is: False

The correct response is that a greater tolerance for alcohol does not lower a person's Blood Alcohol Concentration (BAC). BAC measures the actual amount of alcohol in a person's bloodstream, typically expressed as a percentage. A person's level of tolerance refers to their body's ability to handle and function under the influence of alcohol. Even if someone has a high tolerance and can drink larger amounts without exhibiting typical signs of intoxication, the physiological effects of alcohol on their body do not change the BAC level. Therefore, regardless of tolerance, the alcohol consumed will still contribute to an individual’s BAC based on the amount ingested, body weight, metabolic rate, and other factors. This misunderstanding of tolerance and BAC can lead to serious safety issues, as someone with high tolerance may underestimate their impairment while their BAC remains elevated.
