Florida DMV Drug And Alcohol Practice Test

A person who has developed a high tolerance to a drug has adapted to the presence of that substance in their system, often requiring larger quantities to achieve the same effects. This situation increases the risk of overdose because they may consume amounts that exceed their previous limits, mistakenly believing they are safe due to their tolerance. In many cases, a person may significantly increase their dosage, disregarding the potential dangers, leading to severe health consequences including death. This phenomenon is particularly common with drugs that depress the central nervous system, like opioids, where the margin between a therapeutic dose and a lethal dose narrows as tolerance builds. The other options do not capture the reality that high tolerance consistently raises overdose risk, regardless of the drug type, making the original statement accurate.
